error: 'Flutter/Flutter.h' file not found when running ios build

Question

I've seen this question asked a lot, but none of the solutions I've found have worked for me. As of this week I started getting errors like:

url_launcher-5.7.10/ios/Classes/FLTURLLauncherPlugin.h:5:9: fatal error: 'Flutter/Flutter.h' file not found

It's not always from the url_launcher package. It seems to just cycle through which package it's going to throw that error from. I've tried the following things:

• Removing the ios/Flutter/Flutter.podspec file and running flutter clean
• Toggled between master, stable and beta Flutter builds in combination with removing the Flutter.podspec.
• Removing the whole ios directory and running flutter create . to re-create.
• Re-generating Podfile.
• Trying different versions of the packages that wind up throwing the error.
• Various combinations of the above listed items.

Nothing seems to work, so I'm at a bit of a loss here. The android app is still building fine.

Answer 1

I am using the share extension and none of the answers on SO worked for me. What did work was adjusting my Runner build phases so that they are in the order, as seen in the image.

Answer 2

I recently had this issue, executing these commands in Terminal helped me to resolve the issue.

$ rm ios/Flutter/Flutter.podspec
$ rm -fr ios/Pods
$ rm ios/Podfile
$ flutter clean
