How to access Internal Storage of Android in Flutter

Question

In android we use getFileDir() and getCacheDir() for accessing the Internal Storage. I can see that there's a path_provider plugin that I can use but I can only figure out getTemporaryDirectory() which is analogous to getCacheDir() of android. So is there any alternative way of doing what getFileDir() does in Android.

Is there any other way to do this that I'm aware of, or I'm missing something.

Solution 1

From Flutter sources:

  /// Examples:
  ///
  ///  * iOS: `NSDocumentsDirectory`
  ///  * Android: The AppData directory.
  static Future<Directory> getApplicationDocumentsDirectory() async {
    return new Directory((await _pathProviderProxy.ptr.applicationDocumentsDirectory()).path);

Solution 2

To get internal storage directory path: For Legacy Use these flutter plugin that provides external storage path and external public storage path, ext_storage: ^latest_ver

String path = await ExtStorage.getExternalStoragePublicDirectory(
        ExtStorage.DIRECTORY_DOWNLOADS);

Details:https://pub.dev/packages/ext_storage

external_path:^latest_ver, For NullSafety external_path is a flutter plugin that provides internal, external storage path and external public storage path,

String path=await ExternalPath.getExternalStoragePublicDirectory(
        ExternalPath.DIRECTORY_DOWNLOADS);

Details:https://pub.dev/packages/external_path

@Mosbah It isn't really same as getFileDir because it returns path data/data/your_app_package/files whereas getApplicationDocumentDirectory returns path data/data/your_app_package/flutter/app_flutter, though we can use app_flutter directory instead of files without any issue

@Mosbah can you provide full example of your code? cause I tried your code but I neet to define _pathProviderProxy
