datasetSelectFile function

Future<String> datasetSelectFile()

Implementation

Future<String> datasetSelectFile() async {
  // Use the [FilePicker] to select a file asynchronously so as not to block the
  // main UI thread.

  FilePickerResult? result = await FilePicker.platform.pickFiles(
    dialogTitle: 'Choose a csv/txt file to load as your dataset.',
    type: FileType.custom,
    allowedExtensions: ['csv', 'txt'],
  );

  String path = '';

  if (result != null) {
    // If a file was selected then extract the path from the selected file.

    path = result.files.single.path!;
  }

  return path;
}
