Android #
You need to ask for storage permission to save an image to the gallery. You can handle the storage permission using flutter_permission_handler.
AndroidManifest.xml file need to add the following permission:
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
tools:ignore="ScopedStorage" />

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />

Example #
Access permission(use permission_handler)
bool androidExistNotSave = false;
bool isGranted;
if (Platform.isAndroid) {
final deviceInfoPlugin = DeviceInfoPlugin();
final deviceInfo = await deviceInfoPlugin.androidInfo;
final sdkInt = deviceInfo.version.sdkInt;
/// [androidExistNotSave]
/// On Android, if true, the save path already exists, it is not saved. Otherwise, it is saved
/// 在安卓平台上,如果是true,则保存路径已存在就不在保存,否则保存
/// is androidExistNotSave = true,write as follows:
if (androidExistNotSave) {
isGranted = await (sdkInt > 33 ? Permission.photos : Permission.storage).request().isGranted;
} else {
/// is androidExistNotSave = false,write as follows:
isGranted = sdkInt < 29 ? await Permission.storage.request().isGranted : true;
}
} else {
isGranted = await Permission.photosAddOnly.request().isGranted;
