version 1.0.1

Generates Dart code to automatically check for a new version of the current package. Your project should depend on http. The output code is platform-independent.

One final field is generated: PACKAGE_VERSION - The package's active version. Two methods are generated:

  • fetchCurrentVersion: Asks the Pub API what the latest version of the package is.
  • checkForUpdate: Compares PACKAGE_VERSION to the result of fetchCurrentVersion and returns null if no update is available. Otherwise, the new version will be returned.


Generate from the project pubspec.yaml:

import 'package:build_runner/build_runner.dart';
import 'package:check_for_update/builder.dart';

final PhaseGroup phaseGroup = new PhaseGroup.singleAction(
    new CheckForUpdateBuilder(),
    new InputSet('example', const ['pubspec.yaml']));

You can add the output to a subdirectory, i.e. lib:

new CheckForUpdateBuilder(subDirectory: 'lib')


Specifying a specific package name to scan for updates:

new CheckForUpdateBuilder(packageName: 'shelf')

Specifying a custom Pub API URL:

new CheckForUpdateBuilder(pubApiRoot: '')

Specifying a specific version to check against:

new CheckForUpdateBuilder(currentVersion: new Version(1, 2, 0, pre: 'alpha.6'))
