iOS Flutter Application Won't Launch; 'fatal error: 'camera/CameraPlugin.h' file not found'?

Question

My Flutter application built on both an Android and iOS device prior. However since implementing the camera plugin, the application will no longer build on the iOS device.

So far I have tried:

• Commenting out the use_frameworks! in the Podfile and tried both pod update and pod clean.
• And adding the permissions into the iOS Info.plist file.

The code I'm running is just a default flutter application with a tab that contains the example code from https://pub.dartlang.org/packages/camera.

As you can see, it launches fine on my Android phone. However trying to run it on iOS does not work. Does anyone know how to fix this?

Solution 1

I had the same issue. I fixed by running pod install within my project's /ios directory

Solution 2

I would suggest to everyone who still has these issues to do the following steps:

1. Open the ios folder
2. Double click on the Runner.xcworkspace (NOT Runner.xcodeproj!)
3. Pod Install
4. Build

The problem is that the cam plugin isn't in the scope of the Runner.xcodeproj.

Solution 3

Did you updated your Info.plist for using the camera plugin? If not,

Add two rows to the ios/Runner/Info.plist:

one with the keyPrivacy - Camera Usage Descriptionand a usage description. and one with the key Privacy - Microphone Usage Descriptionand a usage description. Or in text format add the key:

<key>NSCameraUsageDescription</key> <string>Can I use the camera please?</string> <key>NSMicrophoneUsageDescription</key> <string>Can I use the mic please?</string>
