Flutter- how to disable a Button untill the requireed fields are filled

I want to disable a button untill all the required fields are filled. I found similar questions here but all answers are based on making the onPressed property to null. But it does not disable the tap effect.

I want something like this. On disabled mode, clicking on the button won't even cause a Tap effect. Can someone help with a solution?

Solution

  • For a limited number of widgets, you can wrap them in a widget IgnorePointer: when its ignoring property is set to true, the sub-widget (actually, the entire subtree) is not clickable.

    IgnorePointer(
    ignoring: true, // or false
    child: CustomButton(
        onPressed: _login,
        child: Text("Login"),
        ),
)
