'Flutter/Flutter.h' file not found on iOS build

[MercyOdunjo]

Whenever I try to run an iOS build of my app that has the wakelock plus package, I always get this error. What can be done to fix this?

@MercyOdunjo @falniak95 @dekapro9x @MustafaGaber @gokhanvaris I am getting the same error, is this issue resolved. Kindly update.

[MercyOdunjo]

@sunilflutterwebcom I found that this issue is not actually a wakelock problem as shown in @qays3 's build error message. I have had this same error from different other packages on my app at different times. What works for me in recent times, even today, is to do:

flutter clean
flutter pub get
cd ios
pod update

And then run your app normally after the above steps. Sometimes you might have to delete the Podfile.lock file in your ios folder and rerun the steps if it doesn't work the first time. The Podfile.lock and NOT the Podfile itself.
