my_device_info 0.2.0

Privacy-aware, typed Android and iOS device diagnostics in one call, with an opt-in app-scoped identifier.

my_device_info

my_device_info provides privacy-aware, typed Android and iOS diagnostics. Version 0.2.0 can collect a complete snapshot with one native call while keeping the app-scoped identifier opt-in. It targets Flutter 3.47 and Dart 3.13.

Highlights

• One-call DeviceInfoSnapshot API instead of multiple platform round trips.
• Typed platform and operating-system information.
• Model identifier, CPU architecture, supported ABIs, physical-device hint, and Android low-RAM status.
• App-scoped identifier excluded by default and redacted from JSON by default.
• A replaceable platform interface for tests and future platform packages.
• All 0.1.0 getters remain source-compatible.

Supported platforms

Platform	Minimum version	Identifier source
Android	API 24	Settings.Secure.ANDROID_ID
iOS	15.0	UIDevice.identifierForVendor

No runtime permission is required. The identifier is scoped by the operating system; it is not an IMEI, advertising ID, or permanent account identifier. Android scopes ANDROID_ID to the signing key, user, and device on API 26+. iOS shares identifierForVendor between apps from the same vendor. Both values can change, so applications must not treat them as permanent identity.

Installation

dependencies:
  my_device_info: ^0.2.0

Then run:

flutter pub get

Usage

import 'package:flutter/services.dart';
import 'package:my_device_info/my_device_info.dart';

Future<void> loadDeviceInfo() async {
  try {
    final DeviceInfoSnapshot info = await MyDeviceInfo.getInfo();

    print(info.platform);
    print(info.operatingSystem.version);
    print(info.model);
    print(info.architecture);
    print(info.supportedAbis);
    print(info.isPhysicalDevice);

    // JSON output excludes the app-scoped identifier.
    final Map<String, Object?> diagnostics = info.toJson();
  } on PlatformException catch (error) {
    // Handle a platform failure here.
  }
}

Request the app-scoped identifier only for a feature that actually needs it:

final DeviceInfoSnapshot info = await MyDeviceInfo.getInfo(
  includeDeviceIdentifier: true,
);

final String? identifier = info.deviceIdentifier;
final safeJson = info.toJson(); // Still excludes deviceIdentifier.
final fullJson = info.toJson(includeDeviceIdentifier: true);

Do not use the identifier as an authentication secret, advertising identifier, or permanent user identity. Avoid sending fullJson to logs or analytics by default. deviceName is platform-provided and can also contain a user-selected name.

Legacy getters

The static getters from 0.1.0 remain available, including platformVersion, deviceIdentifier, deviceModel, deviceManufacturer, apiLevel, deviceName, productName, cpuName, and hardware. apiLevel still returns an int on Android and the system-version String on iOS for compatibility.

Migrating from 0.1.0

• Prefer MyDeviceInfo.getInfo() when reading more than one field.
• Use the typed operatingSystem.androidApiLevel instead of the legacy dynamic apiLevel getter.
• Enable includeDeviceIdentifier only at the point where it is required.
• JSON serialization now makes identifier inclusion an explicit second opt-in.

Migrating from 0.0.x

• Replace MyDeviceInfo.deviceIMEINumber with MyDeviceInfo.deviceIdentifier. The legacy getter is deprecated and now aliases the app-scoped identifier.
• Remove READ_PHONE_STATE and any phone permission prompt that existed only for this package.
• Android now requires API 24 or later; iOS now requires 15.0 or later.
