Include the version of your package in our source code.

1. Add build_semver to pubspec.yaml. Also make sure there is a version field.

   name: my_pkg
   version: 1.2.3
   dependencies:
     pub_semver: ^2.1.4
   dev_dependencies:
     build_runner: ^1.0.0
     build_semver: ^2.0.0

2. Run a build.

   > dart pub run build_runner build

   lib/src/version.dart will be generated with content:

   // Generated code. Do not modify.
   import 'package:pub_semver/pub_semver.dart';
   
   final packageVersion = Version.parse('1.2.3');

To change the path of the generated file, create a build.yaml in the root of your package. By changing the output option of this builder, the path can be customized:

targets:
  $default:
    builders:
      build_semver:
        options:
          output: lib/src/custom/path/to/version.dart
