copy-large-file

The Plugin copies a large File natively ...

• from the native-Bundle (iOS)...
• from the assets-folder (Android)...

--> ...and places it to your Application Documents Folder

it does the copying only if the file does not already exist at the Application Documents Folder location [same name].

The plugin method created is called copyLargeFile

The return-value of the copyLargeFile method delivers the fullNamePath of the copied (or already existing) large File inside the Application Documents Folder.

Getting Started

1. Inside pubspec.yaml file of your Flutter project, add the following dependency:

dependencies:
  flutter:
    sdk: flutter
  copy_large_file: ^0.0.1

(hint: the version might be different in the meantime. Make sure to include the newest version of the package plugin).

2. Import the package

import 'package:copy_large_file/copy_large_file.dart';

3. usage

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> someMethod() async {
    String fullPathName;
    try {
      String fullPathName = await LargeFileCopy("test.txt").copyLargeFile;
      //...
    } on PlatformException {
      //...
    }
  }

4. native preparations

iOS:

• open your Flutter-project's /ios/Runner.xcworkspace in Xcode
• inside Runner, create a new Group and call it for example "Bundle"
• inside Bundle (or whatever you called your Group), drag and drop your large File (make sure to select "Copy items if needed")
• (optional): to check if all is correct for iOS - go to your Flutter project's ios/Runner/ Folder and see if the added large File is there...

Android:

• open your Flutter-project's /android/my_flutter_project_name_android.iml in Android Studio
• inside app/app/src/main/assets/ folder drag and drop your large file (create assets folder if it is not already there)
• (optional): to check if all is correct for Android - go to your Flutter project's android/src/main/assets/ Folder and see if the added large File is there...
