Version conflicts with Flutter 3.x

Hey there,

I am using mvc_application 8.12.0. I did an update for my app to Flutter 3. After solving some issues, I can not resolve these last three errors, mostly because I think those are dependencies in mvc_application. Do someone know any solution?

Thanks for help me! :)

Hello there!

It would seem Flutter has changed some things allowing the 'null operator' (!) to no longer be necessary.
Allow me to look into it this morning.

Note, they are not errors, I believe, but Warnings. With that, your app should still be able to run...only with warnings.
Regardless, I will look into these Warnings.

Hello Greg,

of course you are right, it is only a warning and not an error, the app builds and starts perfectly :)

Thanks for looking into it!
