how to cache some app data in flutter code example

Example: flutter clear cache programmatically

import 'package:path_provider/path_provider.dart';

Future<void> _deleteCacheDir() async {
  final cacheDir = await getTemporaryDirectory();

  if (cacheDir.existsSync()) {
    cacheDir.deleteSync(recursive: true);
  }
}

Future<void> _deleteAppDir() async {
  final appDir = await getApplicationSupportDirectory();

  if (appDir.existsSync()) {
    appDir.deleteSync(recursive: true);
  }
}
