Flutter application didn't launch in my simulator

I want to launch my flutter application on simulator and I have some problem with it. I have no problems with building the project, but it create an app icon on simulator and launch for one second, then it turns off and nothing happens.

PS: I have two Xcode versions 14 and 14.3 installed, the problem with the project build appeared after updating Xcode to version 14.3

It's my terminal log: Launching lib/main.dart on iPhone 14 Pro Max in debug mode... Running pod install... 1,758ms Running Xcode build...
Xcode build done. 46.8s

Heare my fvm flutter doctor -v log: fvm flutter doctor -v

Solution

  • After some time I found the following error: Exception NSException * "FirebaseApp.configure() could not find a valid GoogleService-Info.plist in your project. Please download one from https://console.firebase.google.com/." 0x00006000005811a0

    Here's how I solved it: Here are the steps to add the GoogleService-Info.plist file to your Xcode project:

    • Go to the Firebase Console at https://console.firebase.google.com/
    • Select your project and click on the gear icon in the top left corner to go to Project settings.
    • In the Project settings page, scroll down to the "Your apps" section and click on the iOS app you want to configure.
    • In the "App settings" section, scroll down to the "GoogleService-Info.plist" section and click on the "Download GoogleService-Info.plist" button.
    • Save the downloaded file to your local computer.
    • Open your Xcode project and drag the downloaded GoogleService-Info.plist file into your Xcode project. Make sure to select the option to copy the file if needed.
    • In Xcode, select your project in the project navigator, and then select your target. In the "General" tab, scroll down to the "Frameworks, Libraries, and Embedded Content" section.
    • Make sure that the GoogleService-Info.plist file is listed under the "Copy Bundle Resources" section. If it's not, click the "+" button and add it.
