For mobile apps (not web), I think yes - Flutter solves a lot of these kinds of issues. As with any project, don't just blindly add a lot of dependencies as they may vary in quality and stability, but overall you deal with two things; Dart and Flutter, and it's quite refreshing.

Not as good as native, but if you're going to go cross platform due to various reasons such as development costs, then it's the way to go.
