Please help me with dependencies problem in Flutter. Says build failed because of something related-CodePudding

I am running into a problem when trying to build my flutter app. I am using VS Code and the latest versions of Flutter and Dart. I think I have a problem with dependencies, but not sure. I have the following dependencies in my pubspec.yaml file.

http: ^0.13.4 youtube_player_flutter: ^8.0.0 percent_indicator: ^3.4.0 endless: ^1.6.0 flutter_staggered_grid_view: ^0.6.1 transparent_image: accordion: ^2.2.3 like_button: ^2.0.4 easy_firebase_auth: ^3.2.0 flutter_inappwebview: ^5.4.3 7 webview_flutter: ^3.0.4 firebase_core: ^1.6.0 cloud_firestore: ^2.5.1 url_launcher: ^6.1.2 geocoding: ^2.0.4 sign_in_with_apple: ^3.3.0

I run into a problem when I do a flutter build. I get the following error messages:

**Could not build the precompiled application for the device.

Error launching application on iPhone.

I tried deleting .g.dart and running all the solutions I could find for similar problems but nothing works. It all seemed to occur after I added the following to my info.plist but not sure if this is related or not.*

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>comgooglemaps</string>
</array>

Also getting the following when I do a flutter run in vs code's output window but not sure if it is related:

I am pretty new to Flutter & Dart. Does anyone know what I can do?

CodePudding user response：

I have similar error and after many tries I solved in this way:

Update MacOS
Update Xcode and command lines tools
Run flutter pub upgrade, flutter pub get in the project folder
Delete podfile.lock in ios folder of the project
Run cd ios, pod repo update, pod install in the project folder
