Solution

The reason you get this is that you use flutter_widget_from_html, that has no null safe version yet, this package depends on old version of chewie (v0.10.4), that uses deprecated property of Scaffold resizeToAvoidBottomPadding.

What you can do is to downgrade your Flutter SDK to pre null-safety version, or rewrite your code without using flutter_widget_from_html package in favor for example chewie, that already has null safety widget.

You can check more info about migrating to null safety here.

If you are willing to downgrade your SDK to pre-null safety you can use this answer.

rename resizeToAvoidBottomPadding to resizeToAvoidBottomInset in your Scaffold resizeToAvoidBottomPadding is deprecated in favor of inset one

I searched with vsCode for <code>resizeToAvoidBottomPadding</code> but it didn't find anything.

[Simon Sot]

sorry I wasnt paing enough attention, seems like the problem in chewie package that is v 0.10.4 and not null safe yet, you shure this is full list of pubspec.yaml file? No chewie: ^0.10.4 there?

[t3nsa]

I forgot to add add_2_calendar: ^2.0.1 but I checked and no chewie

[t3nsa]

Thanks I'll try this. And if it works I'll mark this as the correct answer

[Simon Sot]

@t3nsa wait a bit, I just found that they have beta null safety, change version to flutter_widget_from_html: ^0.6.0 in your pubspec.yaml, run flutter pub get and try again.

[t3nsa]

it says that version 0.6.0 doesn't exist

[Simon Sot]

@t3nsa pub.dev/packages/flutter_widget_from_html/versions/… try flutter_widget_from_html: ^0.6.0-rc.2021031201

[t3nsa]

I've tried but I get error that version solving failed and I've tried to change the version but couldn't get it to work

[t3nsa]

I went to beta by mistake and after that I changed back to stable and I got these errors that I mentioned in my question
