[@wakanimeashita2887]

can you please explain why you added an exclamation point "!" after the value in .hasMatch(value!) I'm getting errors because of that I don't understand why

[@dbestech]

Hi Ashita, it tells the compiler that, it's null safe. It means the variable value is not null. If you get this error then it's a version problem of your dart language.

showSnackBar isn't available anymore, idk what to do

[@dbestech]

ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text("your text")));
this could help

[@robertomejia3124]

how about validate a form with a stepper ? is it similar ? pls help :)

[@dbestech]

Hi Roberto, I haven't used stepper. You can try with it, if you want to

[@justamandd]

It's the same, but you put "_formKey.currentState!.validate()" in onStepContinue, if is validated you increment one in you index var

Is this a tutorial on validation for flutter fields or a regex tutorial?

[@dbestech]

a bit of regex used.

[@sheralikhtk5200]

this doesnt work with a custom textfield

[@dbestech]

Maybe need a little tweak. But I am not sure about your exact needs. giving more info would help me.

[@trevorfranks69]

where's the submit button bro you just skipped it at the 14:00 mark

[@dbestech]

I think I explain it later

[@premtamang709]

Title says "TextField Validation" but, TextField is not even mentioned in video. What a tragedy. Title should be changed to "TextFormField() Validation " rather. Expectation VS Reality

[@dbestech]

Hi Prem, I will change the title. Thank you
