How to debug a mobile QML application in production?

Question

QML

1. How to generate and collect crash reports? Maybe there is a service?
   
2. And what is logged to recreate the picture later? Only operations on objects and transitions between pages?
   
3. If the layout went wrong somewhere, the application started working strangely or just went into an unexpected state, I want to have a button "Take a screenshot, collect information and send it to the developer." Maybe there are some ready-made solutions or best practices?
   

Answer 1

1) Google breakpad + sending logic to your server.
2) Depends on your imagination. If all the logic is in C++, then the call stack is enough
3) doc.qt.io/qt-5/qquickwindow.html#grabWindow
