Getting Started

To use the Utilities-Flutter package, initialize it in your main.dart file. This package simplifies the setup of common Flutter functionalities such as localization, themes, and navigation.

Example main.dart

Future<void> main() async {
  await initUtilities(
    apiKey: "your_api_key",
    // Optional: Add API key for HTTP interceptor
    firebaseOptions: null,
    // Optional: Firebase options
    safeDevice: true,
    // Optional: Enable security checks for Android/iOS
    protectDataLeaking: true,
    // Optional: Prevent data leaking
    preventScreenShot: true,
    // Optional: Prevent screenshots
    deviceOrientations: [DeviceOrientation.portraitUp], // Optional: Set device orientations
  );
  runApp(
    UMaterialApp(
      localizationsDelegates: const <LocalizationsDelegate<dynamic>>[
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
        GlobalCupertinoLocalizations.delegate,
        S.delegate,
      ],
      supportedLocales: const <Locale>[Locale("en")],
      locale: Locale(ULocalStorage.getString(UConstants.locale) ?? "en"),
      lightTheme: AppThemes.lightTheme,
      darkTheme: AppThemes.darkTheme,
      home: const SplashPage(),
    ),
  );
}

Features

UMaterialApp

A wrapper around GetMaterialApp from the GetX package, providing default implementations for theming, localization, and loading dialogs. All parameters are required for simplicity.

UClipboard

Manage clipboard operations easily.

UClipboard.set
("some text
"
); // Set text to clipboard
String? text = await UClipboard.getText(); // Get text from clipboard

UFile

Handle file picking and image cropping with ease.

// File Picker
UFile.showFilePicker(
allowCompression: true,
allowedExtensions: ["png", "jpg", "JPEG"],
allowMultiple: true,
dialogTitle: "Pick Some Awesome Image",
fileType: FileType.image,
action: (List<FileData> files) {
// Handle picked files
},
);

// Image Cropper
UFile.cropImage(
filePath: "filePath",
toolbarColor: Colors.purple,
cropAspectRatio: const CropAspectRatio(ratioX: 1, ratioY: 2),
cropStyle: CropStyle.circle,
androidUiSettings: AndroidUiSettings(hideBottomControls: true),
action: (FileData file) {
// Handle cropped image
},
);

Http Interceptor

Make HTTP requests with a built-in interceptor.

httpRequest(
url: "${AppConstants.baseUrlPractino}GetReportsByMobile/$nationalCode",
httpMethod: EHttpMethod.get,
action: (Response response) {
if ((response.bodyString ?? "").length >= 50) {
action(LifeReportItemsResponse.fromJson('{"items": ${response.bodyString!}}'));
} else {
action(null);
}
},
error: (Response response) {
// Handle error
},
cacheExpireDate
:
cacheExpireDate
,
);

ULaunch

Easily share content or open external apps and URLs.

ULaunch.email("[e-mail]", "hello");
ULaunch.call("1234567890");
ULaunch.sms("1234567890", "some text");
ULaunch.launchInstagram("sinamn75");
ULaunch.launchTelegram("sinamn75");
ULaunch.launchWhatsApp("1234567890");
ULaunch.launchURL("https://sinamn75.com");
ULaunch.shareText("some text");
ULaunch.shareWidget(widget: const CircleAvatar());
ULaunch.launchMap(35.37651, 55.753325);
ULaunch.shareWithTelegram("some text");
ULaunch.shareWithWhatsapp("some text");
ULaunch.shareWithEmail("some text");

ULoading

Display simple loading dialogs using flutter_easyloading.

ULoading.showLoading
(); // Show loading dialog
ULoading.dismissLoading
(); // Dismiss loading dialog
ULoading.showError
(); // Show error dialog
bool isLoading = ULoading.isLoadingShow(); // Check if loading dialog is visible

ULocalAuth

Handle biometric authentication with local_auth.

bool canAuthenticate = await
ULocalAuth.canAuthenticate
();

List<BiometricType> biometrics = await
ULocalAuth.availableBiometrics
();
await ULocalAuth.authenticate(
biometricOnly: true,
localizedReason: "just for fun",
sensitiveTransaction: true,
stickyAuth: true,
useErrorDialogs: true,
);

ULocalStorage

Manage local storage with shared_preferences.

ULocalStorage.set
("key1
"
,
"
value
"
);
ULocalStorage.set("key2", 1);
ULocalStorage.set("key3", 4.5);
ULocalStorage.set("key4", true);

String? key1 = ULocalStorage.getString("key1");
int? key2 = ULocalStorage.getInt("key2");
double? key3 = ULocalStorage.getDouble("key3");
bool? key4 = ULocalStorage.getBool("key4
"
);

ULocation

Get the user's location with geolocator.

Position? position = await
ULocation.getUserLocation
();

UNavigator

Navigate between pages without context.

UNavigator.push
(
const ProfilePage());
UNavigator.off(const ProfilePage(), preventDuplicates: false);
UNavigator.offAll(const ProfilePage(), milliSecondDelay: 100, transition: Transition.fadeIn);
UNavigator.dialog(const ProfilePage());
UNavigator.dialogAlert(const ProfilePage());
UNavigator.back();

UNetwork

Check network and connection status.

bool hasBluetooth = await
UNetwork.hasBluetooth
();
bool hasCellular = await UNetwork.hasCellular();
bool hasEthernet = await UNetwork.hasEthernet();
bool hasWifi = await UNetwork.hasWifi();
bool hasVpn = await UNetwork.hasVpn();
bool hasNetworkConnection = await UNetwork.hasNetworkConnection();

UNotification

Show simple notifications.

UNotification.showNotification
(
title: "title",
message: "message",
onNotificationTap: (NotificationResponse response) {
print(response.id);
print(response.actionId);
print(response.input);
print(response.payload);
},
);

UAppUtils

Utilities for app and device information.

String appBuildNumber = UApp.buildNumber;
String appVersion = UApp.version;
String appName = UApp.name;
String appPackageName = UApp.packageName;

bool isAndroid = UApp.isAndroid;
bool isIos = UApp.isIos;
bool isWeb = UApp.isWeb;
bool isWindows = UApp.isWindows;
bool isMacOs = UApp.isMacOs;
bool isMobile = UApp.isMobile;
bool isPwa = UApp.isPwa;
bool isDesktopSize = UApp.isDesktopSize();
bool isLandScape = UApp.isLandScape();
bool isPortrait = UApp.isPortrait();

UApp.switchTheme
(); // Toggle between light and dark themes
UApp.updateLocale
(
const
Locale
(
"
fa
"
)
); // Update app locale

Extensions

Simplify date handling with DateExtension.

DateTime dateTime = DateTime(2000);
String dateTimeString = dateTime.toIso8601String();

Jalali jalali = dateTime.toJalali();
Gregorian gregorian = jalali.toGregorian();

String compactDate = jalali.formatCompactDate();
String fullDate = jalali.formatFullDate();
String monthYear = jalali.formatMonthYear();
String year = jalali.formatYear();
String shortDate = jalali.formatShortDate();

String jalaliCompact = dateTimeString.toJalaliCompactDateString();
String jalaliDate = dateTimeString.toJalaliDateString();
String jalaliFull = dateTimeString.toJalaliDateTimeFull();
String day = dateTimeString.getDay();
String yearStr = dateTimeString.getYear();
String minute = dateTimeString.getMinute();
