Schedule

Construct a GTFSDataset, populate (load in memory) its primary bindings, enjoy.

import 'package:gtfs_bindings/schedule.dart';
import 'package:path_provider/path_provider.dart';

Future<void> main() async {
  final dataset = DownloadableDataset(uri); // Place the URL to the dataset here.
  await dataset.pipe(tempDir: await getTemporaryDirectory()); // Will download and cache the dataset (do not fill tempDir while on Web).
  await dataset.populateList(dataset.primaryBindings); // Will load the main small files into memory for faster access.
}

Additional information

WIP: THIS IS NOT STABLE. The API may change at any instant. Please wait for 1.0.0 to start deeply integrating any function. The actual APIs to query data are stable
