Flutter plugin wrapping the official E-IMZO Mobile SDK for Uzbekistan electronic signatures. Supports PFX/QR/NFC ID-card/USB token signing and eimzo:// deep links.

More...

1.2.1 #

πŸ”Œ USB token signing fixed β€” verified end-to-end on a physical FEITIAN JavaCard Token V1.0.

  • Bundled the missing native-SDK dependency jars. 1.2.0 shipped only the core SDK classes; the FEITIAN FTReader, ID-card applet and pfx2qr jars were absent, so USB-token signing crashed with NoClassDefFoundError: com.ftsafe...FTException. The plugin now bundles all four jars.
  • Updated bundled SDK to 1.2.8, which fixes the FEITIAN 2.0.1.7 USB flow: permission-request race, automatic readerFind() retry after the grant, reader addressing by UsbDevice name, and direct slot-status detection for tokens without an interrupt endpoint.
  • Added R8 consumer rules for com.ftsafe.** and uz.yt.idcard.applet.** so release builds keep the JNI-referenced reader classes.

1.2.0 #

  • πŸ“ Android: 16 KB page size muvofiqligi (Android 15+). Bundled native Android SDK bumped eimzo-sdk 1.2.6 β†’ 1.2.7. Android 15+ va 16 KB xotira sahifali qurilmalar native .so larning ELF LOAD segmentlari 16 KB ga tekislanishini talab qiladi (Google Play SDK 35 uchun 2025-yil 1-noyabrdan majburiy). Avval qurilma quyidagi ogohlantirishni ko'rsatardi: 
    Π‘Π»Π΅Π΄ΡƒΡŽΡ‰ΠΈΠ΅ Π±ΠΈΠ±Π»ΠΈΠΎΡ‚Π΅ΠΊΠΈ Π½Π΅ Π²Ρ‹Ρ€ΠΎΠ²Π½Π΅Π½Ρ‹ ΠΏΠΎ 16 ΠšΠ‘:
  libgojni.so, libFTReaderPCSC_*.so
    Tuzatishlar:
    • libgojni.so (pfx2qr) Go manbasidan 16 KB alignment bilan qayta build qilindi.
    • FEITIAN kutubxonasi 1.0.9.6 β†’ 2.0.1.7 ga yangilandi β€” FEITIAN'ning rasmiy 16 KB tekislangan SDK'si. Ikkala lib ham endi 16 KB ELF.
    • libgojni.so va pfx2qr.jar bundled tartibda saqlanib qoldi.
  • ⚠️ Integratorlar uchun: to'liq 16 KB muvofiqlik (yakuniy APK ZIP alignment) uchun ilovangizda AGP 8.5.1+ ishlating β€” eski AGP native lib'larni 4 KB ga zipalign qiladi.
  • ℹ️ USB token imzolash FEITIAN 2.0.1.7 API'ga o'tdi.

1.1.9 #

  • πŸ”’ Android: muddati tugagan sertifikat bilan imzolash bloklandi. Bundled native Android SDK bumped eimzo-sdk 1.2.5 β†’ 1.2.6.

    • Muddati o'tgan (validTo sanasi kelgan) kalit kartochkasida qizil "Muddati tugagan" badge chiqadi, Home'da IMZOLASH tugmasi o'chiriladi va kartochka xira ko'rinadi. "Mening kalitlarim" ro'yxatida ham har bir muddati o'tgan kartochka belgilanadi.
    • Defence-in-depth: tugma holati o'tib ketsa ham, bosilganda "Bu kalit muddati tugagan β€” imzolab bo'lmaydi" toast chiqadi.

  • ✨ iOS: muddati tugagan sertifikat bloki + kalitni bir bosishda tanlash. Bundled native iOS SDK bumped EimzoSDK 1.1.5 β†’ 1.1.6.

    • Muddati o'tgan (validTo sanasi kelgan) sertifikat bilan endi imzolab bo'lmaydi. Kartochka kulrang ko'rinishga o'tadi, qizil "Muddati tugagan" badge chiqadi, IMZOLASH tugmasi o'chiriladi. SDK-core'da ham guard bor (SignError.certExpired) β€” deeplink, QR va auto-sign yo'llari qamralgan.
    • Kalitlar ro'yxatida kartochka ustiga bir marta bosish endi uni darhol faol kalit qilib tanlaydi va Home'ga qaytaradi (avval uzoq bosib "Default qilish" tanlash kerak edi).

    Dart API o'zgarmagan. Migration: cd ios && rm -rf Pods Podfile.lock && pod install

1.1.7 #

  • πŸ› Android: PFX import R8 hot-fix. Bundled native Android SDK bumped eimzo-sdk 1.2.4 β†’ 1.2.5. R8 minification yoqilgan integrator app'larda PFX kalit qo'shganda quyidagi crash bilan to'qnashar edi: 
    F/go/Seq : failed to find method Seq.getRef
F/libc   : Fatal signal 6 (SIGABRT) in Java_go_Seq_init
    Sabab: libgojni.so JNI orqali go.Seq.getRef, go.Seq.incRef metodlarini nom orqali topadi. Consumer R8 ularni Kotlin koddan hech kim chaqirmaganini ko'rib rename/strip qilardi. Plugin consumer-rules.pro ga go.** va pfx2qr.** keep qoidalari qo'shildi β€” endi avtomatik shipga ket.

1.1.6 #

  • πŸ›  Fix: iOS App Store nested framework rejection. Bundled native iOS SDK bumped EimzoSDK 1.1.4 β†’ 1.1.5. Avvalgi versiyalarda Pfx2qr.framework EimzoSDK.framework/Frameworks/ ichida embed qilingan edi va App Store Connect bunday tuzilmani rad etardi: 
    ITMS-90205  contains disallowed nested bundles
ITMS-90206  contains disallowed file 'Frameworks'
ITMS-90035  inner Pfx2qr Mach-O not properly signed
    Plus dSYM yo'qligi haqida warning. Yangi versiyada Pfx2qr.xcframework alohida sibling sifatida App.app/Frameworks/ ostiga joylashadi va dSYM fayllari xcframework ichida ship qilinadi β†’ crash log'lar symbolicate bo'ladi. prepare_command eski nested EimzoSDK.xcframework'ni avtomatik aniqlab tozalaydi va ikkala xcframework'ni qaytadan yuklab oladi. Migration: cd ios && rm -rf Pods Podfile.lock && pod install Dart API o'zgargan emas.

1.1.5 #

  • 🚨 Hot-fix: PFX fayldan import barcha avvalgi versiyalarda buzilgan edi. Bundled native Android SDK bumped eimzo-sdk 1.2.3 β†’ 1.2.4. Fayl orqali kalit qo'shganda quyidagi crash bilan to'qnashar edi: 
    java.lang.UnsatisfiedLinkError: dlopen failed:
  library "libgojni.so" not found
    Sabab: libgojni.so (PFX parsing uchun native lib) Flutter plugin jniLibs ichida yo'q edi. Endi to'g'ridan-to'g'ri bundled (4 ABI Γ— ~4.5 MB).
  • πŸ“¦ APK hajmiga ta'sir: bundled .so fayllar tufayli ~18 MB qo'shildi.

1.1.4 #

  • 🎨 Feature: Android SDK 1.2.3 β€” UX yaxshilanishlar + NFC bug-fixlar. Bundled native Android SDK bumped eimzo-sdk 1.2.2 β†’ 1.2.3.
    • 103-sek deeplink sessiya taymeri. Tashqi eimzo://sign?qc=... deeplink kelganida sarlavhada toza taymer ko'rsatiladi (Sessiya: 1:43 qoldi). Foydalanuvchi kerak bo'lsa kalit qo'shishi va keyin imzolashi mumkin β€” deeplink ushlab turiladi. QR hash endi ekranga chiqarilmaydi (foydalanuvchiga ma'nosiz edi).
    • Orqaga qaytish tugmasi. Home (deeplink mode), AddKey, Keys ekranlarida AppBar back tugmasi.
    • NFC imzolashda Lottie bottom sheet. Endi NFC kalit bilan imzolashda ham kalit qo'shishdagi kabi 3 ta animatsiya (yaqinlashtiring β†’ o'qilmoqda β†’ bajarildi) ko'rsatiladi.
  • πŸ› Tuzatishlar (SDK 1.2.3):
    • NFC tag tashlanmas muammosi: dispatchNfcTag Activity'ning pauseβ†’resume tsiklida fragment topishni boshqa usulda qiladi.
    • disableForegroundDispatch crash try-catch ichida.
    • Sessiya tugaganida app majburan yopilmaydi β€” taymer faqat informatsion.

1.1.3 #

  • ✨ Feature: SDK 1.1.4 β€” 103-soniyalik deeplink sessiyasi. Bundled native iOS SDK bumped EimzoSDK 1.1.3 β†’ 1.1.4. Deeplink orqali ochilgan imzo so'rovi endi darhol imzolanmaydi β€” SDK 103 soniyalik sessiya ochadi va foydalanuvchi shu vaqt davomida kalit qo'shishi (ID karta / PFX / QR / USB token) yoki mavjudini tanlashi va IMZOLASH tugmasini bosib imzolashi mumkin. HomeView yuqorisida live countdown banner ko'rinadi (mm:ss + progress bar, 15 soniya qolganda qizilga o'tadi). Vaqt tugasa "Sessiya muddati tugadi" overlay chiqadi. API o'zgarishi yo'q β€” Dart tomonida hech narsa o'zgarmadi, faqat native side UX o'zgardi.

1.1.2 #

  • πŸ› Fix: SDK 1.1.3 - HomeView orqaga qaytish tugmasi. Bundled native SDK bumped EimzoSDK 1.1.2 β†’ 1.1.3. EImzoView sheet sifatida ochilganda HomeView'da SDK'ni yopadigan tugma yo'q edi β€” hamburger icon funksiyasiz bor edi. Endi chevron.backward orqaga tugmasi sheet'ni @Environment(\.dismiss) orqali yopadi.

1.1.1 #

  • πŸ› Fix: SDK 1.1.2 module dependency. Bundled native SDK bumped EimzoSDK 1.1.1 β†’ 1.1.2. Avvalgi versiyada Unable to resolve module dependency: 'FeitianSDK' compile xatosi chiqayotgan edi. Endi @_implementationOnly import FeitianSDK orqali swiftinterface'dan yashirildi β€” consumer loyihalar muammosiz compile qiladi.

1.1.0 #

  • πŸ”‘ iOS: USB token orqali imzolash qo'shildi. Bundled native SDK bumped EimzoSDK 1.0.4 β†’ 1.1.1. iOS 16+ ning ichki CryptoTokenKit orqali Lightning/USB-C portga ulangan CCID tokenlar (Feitian eJava, ePass2003, Identiv SCR3xx va boshqalar) endi to'g'ridan-to'g'ri ishlaydi β€” token MFi sertifikatlangan bo'lishi shart emas.
    • AddKeyView'da 4-source "USB Token" tugmasi.
    • HomeView auto-detect β€” CCID slot ulanganda "USB Token aniqlandi" banneri.
    • KeyCard'da Token chip.
    • Server tomonidan PKCS#7 qabul qilinishi tasdiqlangan (m.e-imzo.uz).
  • πŸ”’ Security: USB token APIsi license-gated. Barcha kirish nuqtalar LicenseEnforcement.ensureAllowed() orqali o'tadi.
  • Cheklov: Lightning iPhone'da Apple Lightning-to-USB Camera Adapter (yoki MFi-certified ekvivalent) kerak. USB-C iPhone 15+ Pro / iPad'da to'g'ridan-to'g'ri USB-C β†’ USB-A kabel ishlaydi.
  • Flutter tomonida API o'zgartirish yo'q β€” mavjud openEImzoView() / deeplink flow USB tokenlar uchun ham avtomatik ishlaydi.

1.0.9 #

  • 🧹 Android: EimzoFlutterPlugin.kt tozalandi. Foydalanuvchi uchun ko'rinmas, lekin loyiha sog'lig'i uchun foydali optimizatsiya:
    • Keraksiz Handler/Looper boqimda olib tashlandi β€” EImzoSDK callbacklari allaqachon Dispatchers.Main da chaqiriladi, qo'shimcha mainHandler.post { } qatlami foydasiz edi.
    • requireActivity(result) helper'i ajratildi β€” 4 ta handler'da takrorlangan activity ?: result.error("NO_ACTIVITY", ...) patterni bitta funksiyaga yig'ildi.
    • onDetachedFromEngine da eventChannel.setStreamHandler(null) va eventSink = null qo'shildi β€” yengil memory leak xavfini yopadi.
    • Kanal nomlari va deep-link sxemasi companion object ichida konstantalar sifatida ajratildi.
    • Kotlin compile warning'lar: 3 β†’ 0.

1.0.8 #

  • πŸ”Œ Android: USB ulaganda ilova endi avtomatik ochilmaydi. Avvalgi versiyada USB_DEVICE_ATTACHED intent-filter qo'shilgan edi β€” natijada FEITIAN token ulanishi bilan OS native UI'ni majburan ochib yuborardi. Bu noqulay edi, shuning uchun intent-filter va eimzo_usb_device_filter.xml olib tashlandi. USB token aniqlash hali ham ishlaydi β€” faqat foydalanuvchi native UI'ga o'tganida BroadcastReceiver yoqiladi va tugma faollashadi.
  • Bundled native SDK bumped to eimzo-sdk-1.2.2.

1.0.7 #

  • πŸ”Œ Android: USB token avtomatik aniqlash. "USB Token orqali imzolash" tugmasi endi faqat FEITIAN / CCID smart-card reader telefonga ulanganda faollashadi. SDK USB_DEVICE_ATTACHED / DETACHED broadcastlarini kuzatib, tugmani real vaqtda yoqadi / o'chiradi. Ulanmagan paytda tugma matni "USB tokenni ulang" ga o'zgaradi.
  • πŸͺͺ Android: device-filter + intent-filter. FEITIAN VID (0x096E) uchun res/xml/eimzo_usb_device_filter.xml + EImzoActivity manifestida USB_DEVICE_ATTACHED intent-filter. Token ulanganda OS ilovani avtomatik ochishni taklif qiladi va USB ruxsatini beradi.
  • 🧹 Android: SDK ommaviy API tozalandi. Barcha ichki klasslar (UsbTokenManager, NfcManager, EImzoApiClient, Room DAO/DB, LicenseGuard, QrCryptoManager, ViewModel'lar, va h.k.) internal deb belgilandi. Endi consumer'da faqat zarur APIlar ko'rinadi. Past darajali signUsbHash primitiv olib tashlandi β€” USB sign uchun yagona API signWithUsbToken(pin, deepLink, callback).
  • Bundled native SDK bumped to eimzo-sdk-1.2.1.

1.0.6 #

  • πŸ“š New CONTRIBUTING.md β€” how to report bugs, suggest features, set up the dev environment, and submit PRs. Helps pub.dev's "package score" community signals and gives external contributors a clear on-ramp.
  • 🌐 Opened public GitHub issues calling for help with desktop and web platform support: macOS #1, Windows #2, Linux #3, Web #4.

1.0.5 #

  • πŸ” Security hardening (both platforms).
    • Android: saved passwords are now AES-256-GCM encrypted with an AndroidKeyStore-bound key before being written to Room. Plain SQLite reads on rooted devices yield ciphertext only; the key is bound to the application UID and is invalidated on Clear data. Bundled SDK bumped to eimzo-sdk-1.0.2.
    • Android: the SDK's Room DB and encrypted prefs are now excluded from adb backup / Google Drive cloud backup via android:fullBackupContent + android:dataExtractionRules. Your own app data is untouched β€” only eimzo_keys.db is filtered.
    • iOS: keys.json written with NSFileProtectionCompleteUntilFirstUserAuthentication. Pre-first- unlock the file is OS-encrypted; backup / jailbreak extraction yields opaque ciphertext.

1.0.4 #

  • πŸ“ Android setup section rewritten: clearer build.gradle requirements (Java 17 + desugaring + minSdk 24), explanations of why each piece is needed, note on launchMode="singleTop" and Material theme pitfalls.

1.0.3 #

  • πŸ“ README usage and API sections rewritten β€” old init / getInitialDeeplink / onNewDeeplink snippet was missing the openSignUi call that actually presents the SDK. New section shows the two real flows: open-from-button and open-from-external-deeplink. No code changes.

1.0.2 #

  • 🍎 iOS support added. The plugin now bundles the closed-source EimzoSDK.xcframework (downloaded from the public release on pod install) and exposes the same openSignUi(deepLink:) API on iOS. Requires iOS 16+.
  • The native iOS UI mirrors the Android SDK 1:1: Home, Cards (key list), PFX/QR/NFC import, deep-link auto-sign, in-app QR scan with "Domen va hesh kod" confirmation bottom sheet.
  • Example app extended with iOS platform (example/ios/) β€” same two buttons work on both platforms.
  • See README for iOS-specific setup: minimum deployment target, NFC entitlement, Info.plist permissions, eimzo:// URL scheme.

1.0.1 #

  • Bundled native SDK bumped to eimzo-sdk-1.0.1.
  • Fix: PFX/QR key import crashed with JsonIOException: Abstract classes can't be instantiated! Class name: uz.eimzo.sdk.network.JsonRpcResponse after the cert-info HTTP round-trip β€” R8 was stripping the no-arg constructors of the Gson-deserialized network DTOs. Added explicit -keep rules for all uz.eimzo.sdk.network.* DTOs (JsonRpcRequest/Response, CertInfoParams/Result, SiteInfoParams/Result, SendPkcs7Params, Pkcs7Result).
  • Fix: ClassNotFoundException: androidx.viewbinding.ViewBinding at runtime β€” added explicit api 'androidx.databinding:viewbinding:8.1.0' to the plugin's Gradle dependencies.
  • Fix: NoClassDefFoundError: pfx2qr.Pfx2qr during PFX import β€” bundled pfx2qr.jar and the libgojni.so native library (all 4 ABIs) directly into the plugin so consumers don't need any extra Maven repo.
  • New native bridge method openSignUi({String? deepLink}) β€” launches the full native EImzoActivity (Home + Keys + AddKey + sign flow). Optional deep-link argument jumps straight into the sign flow.
  • Example app simplified to two buttons: "Open E-IMZO native UI" and "Open with deep link (sign flow)".
  • Verbose diagnostic logging added to EImzoSDK.import* and EImzoApiClient.rpcCall (bakes exception class + stack into the log message string so R8 can't drop it).

1.0.0 #

BREAKING: Rewritten as a thin wrapper around the official E-IMZO Mobile SDK. The bundled eimzo-sdk-1.0.0 native SDK (classes + resources + jniLibs) owns all signing / key-management UI; this plugin just initializes it on the host activity and forwards deep links into Dart.

  • New singleton entry point: EimzoFlutter.instance (the old static API is gone).
  • Three-method API: init({EimzoConfig}) (runs EImzoSDK.checkLicenseAndInit), getInitialDeeplink(), onNewDeeplink().
  • EimzoConfig exposes isTestMode, productionApiUrl, testApiUrl.
  • EimzoException wraps platform errors.
  • Deep-link scheme host changed from eimzo://open to eimzo://sign (per new SDK).
  • Android: dropped uz.yt.idcard.eimzo:flutter_debug/release dependency and the nexus.yt.uz repository requirement. AAR contents are merged into the plugin (classes, res, jniLibs, manifest) plus transitive deps (kotlinx-coroutines, AndroidX core/appcompat/lifecycle/room, Material, OkHttp, Gson, BouncyCastle, Lottie). Consumers don't need any extra Maven repo.
  • AGP androidResources.additionalParameters '--extra-packages', 'uz.eimzo.sdk' so the bundled SDK can resolve its R class against the merged resources.
  • Removed the separate-Flutter-engine EimzoFlutterActivity β€” deep links are delivered to the host app's MainActivity.
  • Licensing: apps must register their package name at info@yt.uz. Unregistered apps see the SDK's blocked-app screen automatically.

0.2.0 #

  • Android: E-IMZO Flutter modul dependency versiyasi 1.1.3 ga yangilandi (flutter_debug va flutter_release).

0.1.8 #

  • Android: rootProject.allprojects { repositories } bloki olib tashlandi β€” zamonaviy Flutter proyektlardagi dependencyResolutionManagement bilan to'qnashib, build xatosiga va MissingPluginExceptionga olib kelardi.
  • README: Maven repository qo'shish majburiyligi aniq belgilandi.

0.1.7 #

  • README: core library desugaring sozlash bo'limi qo'shildi.

0.1.6 #

  • Android: isCoreLibraryDesugaringEnabled true β€” Groovy sintaksisiga o'tkazildi.

0.1.5 #

  • Android: isCoreLibraryDesugaringEnabled = true compileOptions ga qo'shildi β€” desugaring to'liq yoqildi.

0.1.4 #

  • Android: coreLibraryDesugaring (desugar_jdk_libs:2.1.4) to'g'ri e'lon qilindi.

0.1.3 #

  • Android: coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.4") dependency qo'shildi β€” Java 8+ API desugaring qo'llab-quvvatlash uchun.

0.1.2 #

  • Android: E-IMZO Flutter modul dependency versiyasi 1.0.0 ga tuzatildi.

0.1.1 #

  • Android: E-IMZO Flutter modul dependency versiyasi 1.0.0 ga yangilandi (flutter_debug va flutter_release).

0.1.0 #

  • Initial release.
  • Android: E-IMZO Flutter modulini EimzoFlutterActivity orqali ishga tushirish.
  • openEImzo({String? deeplink}) β€” E-IMZO imzolash ekranini ochadi.
  • getInitialLink() β€” ilova eimzo:// orqali ochilgan bo'lsa dastlabki URL ni qaytaradi.
  • linkStream β€” ilova ochiq turganida kelgan eimzo:// deep linklar oqimi.
