“could not build module 'Foundation'”

Question

Did a search for this question and could not find much help.

"could not build module 'Foundation'"

#import < Foundation/Foundation.h>

Not certain what is the problem. Thank you for any advice.

Answer 1

If using flutter run flutter clean in terminal or in android studio, restart emulator and run app.

Answer 2

I found that if you use some external c / c++ code in your project, you have to remove all the #import in prefix. that's quite headache but it's a true problem
