Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

build_version is a Flutter/Dart package that generates a Dart file containing the current version of a package during the build process. It extracts version information from pubspec.yaml and makes it available as a constant in the application code, enabling runtime access to version details without manual updates. This is particularly useful for debugging, logging, or displaying version numbers in the UI. The package integrates seamlessly with the build_runner and supports multiple platforms including Android, iOS, macOS, Windows, and Linux.

Use cases

  • Displaying app version in settings
  • Logging version info for debugging
  • Automating version injection into code
  • Tracking release versions in builds
  • Enabling version checks in app logic

Key features

  • Auto-generates version constants
  • Extracts version from pubspec.yaml
  • Supports multiple platforms
  • Integrates with build_runner
  • Minimal configuration required

Suitable for

  • Apps needing runtime version access
  • Teams wanting automated version management
  • Projects using build_runner workflows
  • Developers seeking minimal boilerplate
  • CI/CD pipelines requiring version metadata

Considerations

  • Requires build_runner to be set up
  • Version is static after build
  • Not suitable for dynamic version changes
  • May require rebuild on version update
  • Limited to version field in pubspec.yaml

CI Pub Package package publisher

Include the version of your package in our source code.

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

    name: my_pkg
version: 1.2.3
dev_dependencies:
  build_runner: ^1.0.0
  build_version: ^2.0.0

  2. Run a build.

    > dart run build_runner build

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

    // Generated code. Do not modify.
const packageVersion = '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_version:
        options:
          output: lib/src/custom/path/to/version.dart
