Flutter app once I open the app in iOS freeze on the splashscreen

I’ve this downside. I’ve a flutter app which is related to firebase. After I run the app in launch mode with the iphone related it really works wonderful. The app present splashscreen and after that present the house or the login.
The issue seem once I shut/kill the app and I re-open it from the telephone. On this case the app is freezed within the splashscreen. The identical downside occur once I obtain the app from testflight. Somebody may help me to grasp which is the issue or a potential resolution? Or a solution to perceive the issue?

That is the code about the principle file:
