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)
• 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: ^2.0.0

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.

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.

setLiveWallpaper #

Setting live wallpaper requires .mp4 file. Also currently local files are only supported, so download it before calling this function. The method call redirect to native Android live wallpaper setting intent, so no locations are currently supported.

String result;
var file = await DefaultCacheManager().getSingleFile(liveUrl);
// 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.';
}
