Flutter project on Mac (copied from Windows)

Question

I received Flutter project from friend to build iOS version of the app on the Mac (Catalina & Xcode 11.3). The Flutter project is made in Windows and made for Android. Now I should make iOS version on Mac of the same project.

I and my friend are very new to Flutter. I have little experience of Xcode (building exported Unity projects).

I want to understand what Flutter needs to be working. I can create test project and run it in the simulator. But this project doesn't work.

Output of flutter doctor -v seems to be fine:

In order to run your application, type:

  $ cd example
  $ flutter run

Your application code is in example/lib/main.dart.

Your plugin code is in ./lib/TestApp.dart.

Host platform code is in the "android" and "ios" directories under ..
To edit platform code in an IDE see
https://flutter.dev/developing-packages/#edit-plugin-package.

flutter run lib/TestApp.dart

Launching lib/TestApp.dart on iPhone 11 Pro Max in debug mode...
Expected ios/Runner.xcodeproj but this file is missing.
No application found for TargetPlatform.ios.
Is your project missing an ios/Runner/Info.plist?
Consider running "flutter create ." to create one.

flutter build ios lib/alylatu.dart

Expected ios/Runner.xcodeproj but this file is missing.
Application not configured for iOS

I even tried to copy files from test project to TestApp folders, but that doesn't worked.

Should I configure the TestApp project to iOS project? I don't have Brew installed. Should I install that and something else?

Any ideas?

Answer 1

I got a similar error as the following:

      Expected ios/Runner.xcodeproj/project.pbxproj but this file is missing.
      No application found for TargetPlatform.ios.
      Is your project missing an ios/Runner/Info.plist?
      Consider running "flutter create ." to create one.

Problem was that I cloned the project from a Git Repository. project.pbxproj file was in .gitignore. So, I created a new flutter project and copied other files into this.

Answer 2

This worked for me:

1) Create a new flutter project. 2) Run the project and ensure it runs smoothly. 3) Once you verify that the project runs, go to your new project in :

• ProjectDirecectory
• iOS folder

Copy the following:

Runner.xcodeproj and Runner.xcworkspace

Paste these into your old project (Project/ios) then save and run. This worked for me and hope it will help.
