MissingPluginException(No implementation found for method authenticate on channel flutter_web_auth_2)[Bug]: <Choose an appropriate title>

Description

Hi I get this error when calling the authenticate method is a flutter web app hosted on firebase.

"MissingPluginException(No implementation found for method authenticate on channel flutter_web_auth_2)"

This works fine when I run the app locally on my laptop but not when it is hosted. The url i pass to the FlutterWebAuth2.authenticate works correctly when I manually paste into a browser.

Any help much appreciated.

Minimal Reproduction

final result = await FlutterWebAuth2.authenticate( url: updatedUrl, callbackUrlScheme: "my-app");

This is in a flutter web app hosted on firebase. The url works correctly when manually pasted into a browser and also works correctly when run locally.

Exception or Error

MissingPluginException(No implementation found for method authenticate on channel flutter_web_auth_2)

Expected Behaviour

I expect the authenticate method to open a google oauth2 consent url

Could you maybe try the latest 4.x beta version? If that also does not work, I will investigate a bit more

Thanks for your response - I managed to fix this by doing a flutter clean and rebuild of the app and deploying again on v3.1.1 Apologies - I should have done this before raising the issue. Many Thanks
