I have some web development experiences and today I started learning Flutter. I made a really basic app, that displays a time in different countries. It loads very fast, but I want to see how long it takes to open. I found a lot of tutorials about how to do this but I don't understand them. I want to compare the results of my app with results of other apps on my phone, so if you know some apps to test load speed pls send me a link or explain how to do it in another way.
CodePudding user response：
What you're looking for is time to initial display. Time to initial display
ActivityManager: Displayed com.android.myexample/.StartupTiming: 3s534ms (total 1m22s643ms)
Open your logs and filter by Displayed
I dunno what the flutter counterpart is but since it's an activity you're opening it should be the same.
The other way is using Systrace and Perfetto.
