Tools for gauging/measuring some performance metrics.
Currently there‘s only one tool to measure iOS CPU/GPU usages for Flutter’s CI tests. It‘s only tested on Xcode 10 and it’s known that Xcode 11 may not be compatible.
First install Xcode 10.3 (https://developer.apple.com/download/more/), dart, and git. Make sure that pub
, git
, and instruments
are on your path.
Then run:
pub global activate gauge
Connect an iPhone, run a Flutter app on it, and
pub global run gauge ioscpugpu new
Sample output:
gpu: 12.4%, cpu: 22.525%
For more information, try
pub global run gauge help pub global run gauge help ioscpugpu pub global run gauge help ioscpugpu new pub global run gauge help ioscpugpu parse
