Flutter 3.35.0 has officially landed, bringing a host of improvements across web, desktop, accessibility, UI components, and tooling.

This release is special for me — my own contribution is included:

Fix text selection toolbar alignment for RTL languages
by @SalehTZ in #169854

This fix improves the user experience for right-to-left languages like Persian, Arabic and others by ensuring the text selection toolbar aligns correctly, making editing smoother and more intuitive for millions of users.
