Flutter apps profiler. The heroes which are unjustly forgotten

It seems that there's no doubt that Flutter came into development for sure and for a long time.

Three main ideas explain Flutter popularity:

• Fast development, ideal support from the point of view of IDE.
• Bright UI — a rich library of embedded widgets along with the opportunity to create your own custom widgets, allows to create really cool interface with minimal costs.
• Native performance — the application code on Flutter compiles into the ARM machine code with Dart AOT compiler.

If the first two points do not cause any doubt, the question of app performance may be put under doubt for a simple reason — the UI logics code is written be developers. So, we make mistakes which may considerably influence UI performance.

In this talk we will discuss how and with what tools you may find the reasons for bad performance during UI rendering.
