Flutter Form Validation with Provider and Bloc

Validating form input is a common use case in Flutter applications. In this video we'll use the Provider package and RXDart to create and connect backend validation for UI form fields.

This is a great tutorial, Andy's the best!

[wickedgummybear]

Thanks for redoing it! Even with the suggestions I tried and commented on the other video, I still had a hard time getting it to work. Flutter moves so fast in its development.

Excellent tutorial! RxDart is one of the best Flutter libraries! Congratulations!

another great video, learned a lot, great example to step into this concept. Keep them coming! Very effective teaching style.

[rogiergorter]

Thank you. I like your clean way of coding.

Hi, very nice explanation I have used this approach in my project, but facing problem while populating pre-filled values in form and then on update action with those value, controller doesn't get updated with pre-filled value and null is return from controller stream.Please help me how to update controller with initial values.

Hi.. I need to know how to navigate to next screen after submit the form

Where should i get callback to check request is complete or not and If complete navigate to next screen

hi there, I liked the video, actually works nice, but I have a question, how do you delegate all stream values to a event output through the yield of a state? I cannot just call a getter and pass it to the yield CertainState as I used to, in fact I sadly think I have a wrap another getter to take the values out from the streams...

can u do another video that show how to use the library flutter_bloc with rxdart for formvalidation and http logic persist?

[pratikshasisodia]

Very well explained. But could please tell how can we implement this for stateful classes? It will be a great help.

Where’s the cold intro..one of the few I actually like 😺Oh well always good content, thank you sir

[phuocluongtranhong]

Thank you very much! But if I have a lot of screens (ex: login, MyPage, ...). I can create a screen is a bloc or only one bloc?

[Peter-lgmc]

This is probably a dump question, but inside the bloc you defined a dispose method. Shouldn't you call this something like so: (context, value) => value.dispose(), .. ?

[gbvid]

Great tutorial, I always like the neat and easy to read code formatting. It would be good to show how to populate initial values in both text field and stream using a controller in a stateful widget.

[erichughes]

you said you watched that course on flutter which was like 30 hours? is that content still up to date?

[EricOmine]

Thanks for the content. Just a suggestion: can you please increase the font on your IDE in future videos?

If you chill out on the amount of ads, I think it will better help your channel grow.
