built_version

Provides Dart build systems for generating a package version string accessible at compile time.

The builder generates code when it finds members annotated with classes defined in package:built_version_annotation.

Setup

Example

Given a library example.dart with a getter annotated with BuiltVersion:

import 'package:built_version_annotation/built_version_annotation.dart';

part 'example.g.dart';

@BuiltVersion()
String get version => _$PackageVersion;

Building creates the corresponding example.g.dart:

part of 'example.dart';

String get _$PackageVersion => '1.0.0';

The value of _$PackageVersion will be the value found in the project's pubspec.yaml.

Running the code generator

Once you have added the annotations to your code you then need to run the code generator to generate the missing .g.dart generated dart files.

Run > dart run build_runner build in the package directory.

Annotations

The only annotation is [BuiltVersion](). When applied to a getter, a _$PackageVersion code will be generated when you build.

Motivation

Why package:built_version vs. package:package_info_plus? This package offers a build-time value that is accessible in Dart code that is generated from the version code in pubspec.yaml. This value is available for a single plugin/package, as opposed to package_info_plus which takes the value from the current running application.
