easy_semver 1.1.0

Bump and sync a Flutter app's semantic version across pubspec.yaml, the iOS Xcode project and Android Gradle files, and repair drift between them.

easy_semver

Bump a Flutter app's version everywhere it is written, in one command.

A Flutter app's version lives in more than one file, and those copies drift. bumpv updates them together and tells you exactly what moved.

$ bumpv minor
1.2.1+1  ->  1.3.0+1

  pubspec.yaml               1.2.1+1 -> 1.3.0+1
  ios/…/project.pbxproj      FLUTTER_BUILD_NAME: 1.2.1 -> 1.3.0, MARKETING_VERSION: 1.2.1 -> 1.3.0  (Debug, Release, Profile)
  android                    no edit needed — versionName/versionCode come from pubspec.yaml

Done. Review with:  git diff

Why this exists

Bumping pubspec.yaml is usually enough — Flutter feeds versionName/ versionCode on Android and $(FLUTTER_BUILD_NAME)/$(FLUTTER_BUILD_NUMBER) on iOS from it.

Usually. If ios/Runner.xcodeproj/project.pbxproj pins FLUTTER_BUILD_NAME in its build settings — and plenty of projects do, often without anyone noticing — that target-level value overrides the one Flutter generates into Generated.xcconfig. Bump only pubspec.yaml and your pubspec says 1.3.0 while the build you ship to TestFlight is stamped 1.2.1.

bumpv keeps all of it in agreement, and re-running it repairs drift that has already happened.

Install

dart pub global activate easy_semver

If you get bumpv: command not found, add pub's bin directory to your PATH:

export PATH="$HOME/.pub-cache/bin:$PATH"    # add to ~/.zshrc or ~/.bashrc

Or skip PATH entirely: dart pub global run easy_semver:bumpv minor.

Usage

Run it anywhere inside a Flutter project — it walks up to find pubspec.yaml.

bumpv patch                 # 1.2.1 -> 1.2.2
bumpv minor                 # 1.2.1 -> 1.3.0
bumpv major                 # 1.2.1 -> 2.0.0
bumpv 2.4.0                 # set the version exactly
bumpv 2.4.0+7               # set version and build number

Option	Effect
--build N	Set the build number explicitly
--bump-build	Increment the build number
--commit, -c	Commit the updated files (Git projects)
--dry-run	Print what would change, write nothing
--project DIR	Target another directory

The build number is preserved unless you pass --build or --bump-build. App stores reject a repeated build number, so use --bump-build for a release:

bumpv minor --bump-build    # 1.2.1+1 -> 1.3.0+2

Committing the bump

--commit (or -c) commits the files it just wrote:

$ bumpv patch --commit
1.2.1+1  ->  1.2.2+1

  pubspec.yaml               1.2.1+1 -> 1.2.2+1
  ios/…/project.pbxproj      FLUTTER_BUILD_NAME: 1.2.1 -> 1.2.2  (Debug, Release, Profile)
  android                    no edit needed — versionName/versionCode come from pubspec.yaml

Done. Committed:  chore: bump version to 1.2.2

Only the files bumpv wrote go into the commit, so whatever else you have in progress stays exactly where it was — staged or not. If the project isn't a Git repository you get a warning and the bump still stands, and --dry-run wins: nothing is written and nothing is committed.

Repairing drift

Run bumpv with the version you already have. It won't change the version, but it will re-sync the native files and report anything that was out of step:

$ bumpv 1.3.0
1.3.0+1 (unchanged)

  pubspec.yaml               unchanged
  ios/…/project.pbxproj      FLUTTER_BUILD_NAME: 1.2.1 -> 1.3.0  (Debug, Release, Profile)

What it touches

File	Behaviour
pubspec.yaml	version: is rewritten
ios/Runner.xcodeproj/project.pbxproj	FLUTTER_BUILD_NAME, FLUTTER_BUILD_NUMBER, MARKETING_VERSION and CURRENT_PROJECT_VERSION are synced in the app target only — settings the project doesn't declare are left absent, and test targets keep their own version
android/app/build.gradle[.kts]	Hardcoded versionName/versionCode are rewritten (Kotlin DSL and Groovy). When they defer to flutter.versionName/flutter.versionCode, nothing is written and that is reported

Nothing else in those files is altered.

Use it as a library

The updaters are pure functions from file content to file content, so you can drive them from your own release script without inheriting any filesystem assumptions:

import 'package:easy_semver/easy_semver.dart';

final next = Version.tryParse('1.4.0+2')!;

final yaml = updatePubspec(pubspecText, next);

final ios = updateXcodeProject(pbxprojText, next);
print(describeChanges(ios.changes));   // FLUTTER_BUILD_NAME: 1.2.1 -> 1.4.0, …
print(ios.configurations);             // [Debug, Release, Profile]

Not handled

macOS, Windows and Linux desktop targets keep their own version files and are out of scope for now.
