构建 Flutter iOS 应用时出错 - Firebase

Question

My app is not building for the iOS simulator.

I've tried a clean, looks like it's a Firebase issue.

I'm using these versions:

dependencies: flutter: sdk: flutter firebase_core: ^0.5.0 cloud_firestore: ^0.14.0+2 firebase_auth: ^0.18.0+1

In file included from /Users/ramshaw/.pub-cache/hosted/pub.dartlang.org/firebase_core-0.5.0/ios/Classes/FLTFirebasePluginRegistry.m:5:

Could not build the application for the simulator. Error launching application on iPhone 11.

Answer 1

Fixed.

1. Created a new Flutter project
2. Copied over the pub spec.yaml file, checked the app was building.
3. Repeated step 2 for the rest of my lib files, one file at a time.

Why one file at a time?

'cause if I replaced the folder, it did not build.

I'm happy my app is building again but not sure why and that doesn't make me happy.
