troubleshooting some standard issues
question: my app looks janky or stutters.
how do i fix it?
answer: performance issues can cause UI frames
to be janky and/or slow down some operations.
for more information, check out the
performance page.
question: i see a lot of garbage collection (gc) events occurring.
is this a problem?
answer: frequent GC events might display on
the DevTools > memory > memory chart. in most cases,
it’s not a problem.
if your app has frequent background activity with some idle time,
flutter might use that opportunity to collect the created objects
without performance impact.
