Small suggestion: try to add a set of lints (like lints, flutter_lints or very_good_analysis) to catch some of the things that were solved in this PR

Also, try to update the changelog to provide context to version updates

@Zazo032 We only add flutter_lints in the example project, this should be fixed now!

I updated slightly the changelog but we'll do better with next versions. 👌
