[desktop] High memory consumption #90868

Description

@fryette

Details

It consumes too much memory. What we noticed is that if you remove the linter rules, things get a little better. (Up to 3-4 GB)
I'm pretty sure that the flutter team should expect absolutely the same issues with any example project.

Environment
Flutter 2.5.0/2.5.1
Dart 2.14.0

Able to reproduce it stably from 2.0.2 to 2.5.1 on our project.

Target Platform:
macOS(latest stable), Windows 11
