Thank God I have stumbled on your videos, your explanation is awesome. Just what I needed in this time of pandemic with a project at school. I wish you could make a video of register/login using php with mysql database. Thank you and stay cool!

[muhammadanggoran]

Sir, do you know how to solve inactive input connection? I've already tried stackoverflow solution but still didn't work yet

[RRaider]

Hello sir, please support me on this.
I'm working on a school project.
So basically the Thing is. After I save the form



So I need to send it to the user data to the database. While also send auth data. I have however been able to setup an auth already. Please what patten should I submit the form? Thank u

[VladVons]

is it allowed to inherit RaisedButton instead of StatelessWidget ?
class MyRaisedButton extends RaisedButton {}

[kind]

Do we still need setState for assigning value to a variable since we now have onSave and formState.save() ?

[abdallahboucedraya]

I have forms inside PageView, one unique form on each page, and I need to validate them all.
how I can achieve that ?

[StoreRunDotCom]

if (value.length < 4 ) { - The property 'length' can't be unconditionally accessed because the receiver can be 'null'. ALSO onChanged: (value) => setState(() => username = value); - Missing parameter type for 'value'.
