normalizeAssetDir static method
On Android, this will copy the asset dir from the AssetManager into context.filesDir, and return the filesystem path to the newly created dir. Pathnames will be URL-decoded. On iOS, this will return the filesystem path to the asset dir.
Implementation
static Future<String?> normalizeAssetDir(String assetDir) async {
final args = <String, dynamic>{
'assetDir': assetDir,
};
final result = await _channel.invokeMethod('normalizeAssetDir', args);
final String? path = result;
return path;
}
