Explain how to write/run a performance test for a Flutter app

We have our own performance tests (which are public), but we don't really have a good example for developers to use themselves for testing the performance of their app.

One example would be to show an example of replicating the Flutter Gallery missed frames benchmark with a simpler sample app.

Another example could be showing how to benchmark some piece of business logic just like @mraleph showed in his Talk at DartConf.

This bug may be too general to track here, but wanted to write this down for our medium-term docs/examples planning. FYI @mjohnsullivan

Is this covered by
https://flutter.io/docs/testing/ui-performance
https://flutter.io/docs/cookbook/testing/integration/profiling
?

I started writing a codelab on this, but other priorities took precedence.

@sfshaza2 Is the codelab available? Could I get some mock code if not or something reference.

https://flutter.io/docs/cookbook/testing/integration/profiling this doc is useful but needs to be updated to using integration_test.

This exists on the Performance Profiling page.
