Update the flutter version and other packages

[literalEval]

The app no longer works. Most probably it's an issue with one (or more) package versions.
Pubspec needs to be updated.

I just checked, other than flutter_duration_picker, everything works perfectly and the app gets compiled too.
This package certainly needs to be replaced. Would you like to work on this?
Also, check the comment on issue #7 @Literal-Eval

[literalEval]

Yep. I'll work on this.
And about issue #7 , I think instead of downgrading flutter, upgrading plugins would be a more robust solution.

Yep, version updates are much needed. Assigning it to you!

@nb9960 flutter_duration_picker is obsolete. At first I thought of downloading their code and migrating it accordingly, but then I found something similar, https://pub.dev/packages/duration_picker.

I propose to use this plugin instead of flutter_duration_picker.
