Usage

Import the package:

import 'package:fl_cloud_storage/fl_cloud_storage.dart';

Initialize the service you want to use:

final driveService = await CloudStorageService.initialize(
  StorageType.GOOGLE_DRIVE,
  cloudStorageConfig: null, // optional parameter, vendor specific implementation
);

If you need special scopes, read the section for each cloud storage vendor.

1.a) Login:

cloudStorageService.authenticate();

1.b) Ask if the user is logged in:

cloudStorageService.isSignedIn;

1.c) Logout:

cloudStorageService.logout();

4.a) List files on cloud storage:

cloudStorageService.getAllFiles()

Google Drive Cloud Storage

2.) Authorization

By default the app scope is used for Google Drive:

[v3.DriveApi.driveAppdataScope, v3.DriveApi.driveFileScope]

If you need full read and write access, add a cloudStorageConfig:

final driveService = await CloudStorageService.initialize<GoogleDriveScope>(
  StorageType.GOOGLE_DRIVE,
  cloudStorageConfig: GoogleDriveScope.full,
);

Behind the scens this scope is asked for:

[v3.DriveApi.driveAppdataScope, v3.DriveApi.driveFileScope, v3.DriveApi.driveScope]
