[sageata]

Same here.

I did:

rm ios/podfile
pod update

However, it did not fix the issue :(

[JCKodel]

I had the same problem

I fix it by:
Running "flutter channel stable" .
After that, "run pub get"

Done!

This "fixes" nothing! 🤬
We MUST use non stable Flutter channel to build for Windows or Web.

[danvick]

Hi all, this issue has been fixed in v1.8.0.

[buraky84]

still have the same error on all channels(master, stable, dev). latest version 1.8.x

[buraky84]

this worked for me. add this lib entry to pubspec.yaml
flutter_chips_input: ^1.8.0
run the project once.
you can now delete this entry.
run the project again.

looks like there is a temporary issue with pubspec cache causing this error.

The error is still here:

adding flutter_chips_input: ^1.8.0 does not help.

This is a different issue. Check #37 for fix for this.
