With flutter_webview_plugin: ^0.1.5 && latest Flutter update, I got the following error

Failed to build iOS app
Could not build the application for the simulator.

I had to remove flutter_webview_plugin: ^0.1.5 from pubspec.yaml and then run
pod deintegrate
on iOS project

[js1972]

For that error I find the following fixes work:

Copy a suitable profile from Flutter Master (https://github.com/flutter/flutter/tree/master/packages/flutter_tools/templates/cocoapods) to your projects iOS/Podfile and delete iOS/Podfile.lock.
Use the ObjC version if your project wasn’t created with -I swift.
This solution is from Flutter issue flutter/flutter#16036.
