Features

The package allows you to set wallpaper on your Android device asynchronously, in the following ways.

• Set wallpaper from a file path
• Set wallpaper from a URL
• Set wallpaper from a video file (file path)
• Can select locations (HOME, LOCK, BOTH)
• Open native wallpaper chooser
• Minimise your app and go to Android home screen

Installing

1. Depend on it

Add this to your package's pubspec.yaml file:

dependencies:
  async_wallpaper: ^2.1.0

2. Install it

You can install packages from the command line:

with pub:

pub get

with Flutter:

flutter pub get

3. Import it

Now in your Dart code, you can use:

import 'package:async_wallpaper/async_wallpaper.dart';

Usage

AsyncWallpaper is a Class that exposes some methods, variables which you can call to set wallpapers. When you want to set wallpaper simply use it like:

await AsyncWallpaper.setWallpaperFromFile(
    filePath: file.path,
    wallpaperLocation: AsyncWallpaper.HOME_SCREEN,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
);

It needs three arguments -

• filePath – the path of the file to set as wallpaper
• wallpaperLocation – the location where you want to set the wallpaper
• goToHome – a bool, which redirects your app to home screen when wallpaper is set (optional)
• toastDetails: - a ToastDetails object, which contains the details of the toast to be shown when wallpaper is set (optional)
• errorToastDetails: - a ToastDetails object, which contains the details of the toast to be shown when wallpaper is not set or error (optional)

AsyncWallpaper has three locations predefined -

• HOME_SCREEN – set wallpaper on home screen
• LOCK_SCREEN – set wallpaper on lock screen
• BOTH_SCREENS – set wallpaper on both home and lock screen

Detailed Usage

Below is the detailed usage of the package, including all functions defined.

platformVersion

await AsyncWallpaper.platformVersion ?? 'Unknown platform version';

It returns the platform version of the device. Useful for all the Android 11, 12 permission related stuff.

setWallpaperFromFile

Setting wallpaper from a file path, on home screen.

String result;
var file = await DefaultCacheManager().getSingleFile(url);
// Platform messages may fail, so we use a try/catch PlatformException.
try {
    result = await AsyncWallpaper.setWallpaperFromFile(
    filePath: file.path,
    wallpaperLocation: AsyncWallpaper.HOME_SCREEN,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
    )
        ? 'Wallpaper set'
        : 'Failed to get wallpaper.';
} on PlatformException {
    result = 'Failed to get wallpaper.';
}

Setting wallpaper from a file path, on lock screen.

String result;
var file = await DefaultCacheManager().getSingleFile(url);
// Platform messages may fail, so we use a try/catch PlatformException.
try {
    result = await AsyncWallpaper.setWallpaperFromFile(
    filePath: file.path,
    wallpaperLocation: AsyncWallpaper.LOCK_SCREEN,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
    )
        ? 'Wallpaper set'
        : 'Failed to get wallpaper.';
} on PlatformException {
    result = 'Failed to get wallpaper.';
}

Setting wallpaper from a file path, on both screens.

String result;
var file = await DefaultCacheManager().getSingleFile(url);
// Platform messages may fail, so we use a try/catch PlatformException.
try {
    result = await AsyncWallpaper.setWallpaperFromFile(
    filePath: file.path,
    wallpaperLocation: AsyncWallpaper.BOTH_SCREENS,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
    )
        ? 'Wallpaper set'
        : 'Failed to get wallpaper.';
} on PlatformException {
    result = 'Failed to get wallpaper.';
}

Note - You can use the flutter_cache_manager plugin to download the file from the internet, and get the file path.

// Platform messages may fail, so we use a try/catch PlatformException.
try {
    result = await AsyncWallpaper.setLiveWallpaper(
    filePath: file.path,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
    )
        ? 'Wallpaper set'
        : 'Failed to get wallpaper.';
} on PlatformException {
    result = 'Failed to get wallpaper.';
}

openWallpaperChooser

Opens Android native wallpaper chooser.

String result;
// Platform messages may fail, so we use a try/catch PlatformException.

    filePath: file.path,
    goToHome: goToHome,
    toastDetails: ToastDetails.success(),
    errorToastDetails: ToastDetails.error(),
    )

        : 'Failed to open wallpaper chooser.';
} on PlatformException {

}
