I'm waiting for Flutter to stop draining the battery. On my Mac, a single TextField with a blinking cursor inside uses somewhere between 10% and 20% CPU. This is a complete show stopper for me.
Flutter in iOS Simulator will drain my laptop's battery in an hour. It's quite frustrating. Pre-pandemic, I often worked in cafes and libraries and purchased a long power cable to use when I need to work with Flutter and can't get a seat next to an outlet.
I think Flutter Team (and most ppl at Google) are entirely focused on pushing out new features which they can cite on their performance review docs to get higher pay. Few of them focus on user needs. This is why Flutter built Web and Desktop support before finishing Mobile. Flutter Mobile things left undone: no high-quality location module, long-standing bug in camera module on Android, missing Cupertino widgets, a few missing Material widgets (date-time picker), critical info missing from docs, and missing non-trivial examples.
Seems with Flutter being open, the growth of flutter outside of mobile was started by others, with it's being picked up by other teams within google and outside of google.
Teams from Sony, Toyota and Samsung(Tizen) are giving flutter a go on their own.
Also the ubuntu guys are active committers to progress flutter desktop.
I'm simply observing the CPU usage of the Flutter app when a TextField gets the focus. I don't see why it matters whatever else may be hogging the CPU as well.
I tried it on macOS as well as on the iOS simulator and on the web, but I haven't tried the latest version yet. You can try the web version here:
I wouldn’t discard it so easily - flutter does all drawing and compositing on its own, without using system libraries. Could easily be redrawing the whole screen.
