Overview

When you have a add-to-app with multiple flutter engines active at the same time, the devtools takes the first valid isolate and sets it as main, making it impossible to use widget inspector and other tools

Minimal Example App - https://github.com/AshishSingh2001/minimal-add-to-app

Steps to reproduce

• run the android app

cd android_app
./gradlew installDebug

• Attach flutter debugger to the dart VM service (you can get this from logcat)

Issue

In the debugger you will always see homeTab and don't have a way to switch to another tab

The widget inspector is build with keeping normal flutter apps in mind, where only one isolate can be the main isolate, but in add-to-app there can be multiple isolates which can render flutter separately
