Git hooks in Flutter projects with Lefthook

I'm using Flutter for mobile development and, coming from the JavaScript world, I'm used to having Git hooks running checks before a commit or a push using husky and lint-staged.

To accomplish the same with Flutter, I've decided to use Lefthook - the fastest polyglot Git hooks manager out there. Read the introduction post to find out more details about it.

Without further ado, let's see how to use it in our projects.

• Install Lefthook via gem, npm or from source or your OS package manager;
• Define your hooks in the file lefthook.yml: ```yml pre-push: parallel: true commands: tests:

  run: flutter test
  

  linter:

  run: flutter analyze
  

pre-commit: commands: pretty: glob: '*.dart' run: flutter format {staged_files} && git add {staged_files} ```

• Run lefthook install to finish the setup.

And that's it! Now, whenever you commit something, flutter format will run in the staged files and whenever you push commits, flutter test and flutter analyze will run in parallel.

If any of these commands throws an error, the action will be aborted.

Notes

Even though I've demonstrated it with Flutter, Lefthook is "polyglot" and can be used with many other languages and frameworks. It can also run scripts! Check out their documentation for more.

Don't forget to check the Git documentation for more hooks.

If you're using a different solution or have any suggestions to improve this example, feel free to share it in the comments.
