selectFile function

Future<String?> selectFile({
  1. String defaultFileName = 'image.svg',
  2. List<String> allowedExtensions = const ['svg'],
})

Implementation

Future<String?> selectFile({
  String defaultFileName = 'image.svg',
  List<String> allowedExtensions = const ['svg'],
}) async {
  // Use a [FilePicker] to select a file. This is performed asynchronously so as
  // not to block the main UI thread.

  String? result = await FilePicker.platform.saveFile(
    dialogTitle: 'Provide a filename to save the file to',
    fileName: defaultFileName,
    type: FileType.custom,
    allowedExtensions: allowedExtensions,
  );

  return result;
}
