How to Solve error: ‘Flutter/Flutter.h’ file not found when flutter run on iOS?

Solution 1

It’s happening caused by switching from master/dev back to beta/stable. This Solution is worked for me. But make sure to Backup ios/Runner folder before running any commend.

1. Just remove ios/Flutter/Flutter.podspec: rm ios/Flutter/Flutter.podspec
2. Then run flutter clean
3. Run your app again.
4. Boom! Your Error might be solved.

Solution 2

The following commands fixed this behavior:

1. cd ios for going to iOS directory of the flutter app
2. pod deintegrate
3. rm Flutter/Flutter.podspec
4. rm podfile.lock
5. flutter clean
6. flutter run

Solution 3

Just switch the channel from Master to stable. to switch your channel, run this in your terminal:

1. flutter channel stable
2. flutter clean
3. flutter run

Solution 4

Changing PodFile from:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
    config.build_settings['ENABLE_BITCODE'] = 'NO'
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
    end
  end
end

to

post_install do |installer|
  installer.pods_project.targets.each do |target|
