2. Check the current version of path_provider at https://pub.dev/packages/path_provider.
3. Add the dependency to the pubspec.yaml file:

path_provider: ^2.0.1

4. At the top of the main.dart file, import path_provider:

import 'package:path_provider/path_provider.dart';

5. At the top of the _MyHomePageState class, add the State variables that we will use to update the user interface:

String documentsPath='';
String tempPath='';

6. Still in the _MyHomePageState class, add the method for retrieving the temporary and documents directories:

Future getPaths() async {
    final docDir = await getApplicationDocumentsDirectory();
    final tempDir = await getTemporaryDirectory();
        setState(() {
            documentsPath = docDir.path;
            tempPath = tempDir.path;
        });
}
