toFile method
Converts the state history to a JSON file.
Returns a File representing the JSON file containing the state history
of the editor. The optional path
parameter specifies the path where
the file should be saved. If not provided, the file will be saved in
the system's temporary directory with the default name 'editor_state_history.json'.
Implementation
Future<File> toFile({String? path}) async {
// Get the system's temporary directory
String tempDir = Directory.systemTemp.path;
String filePath = path ?? '$tempDir/editor_state_history.json';
// Create a temporary file
File tempFile = File(filePath);
// Write JSON String to the temporary file
await tempFile.writeAsString(await toJson());
if (kDebugMode) {
debugPrint('Export state history to file location: $filePath');
}
return tempFile;
