How do I disable a Button in Flutter?

Question

I\'m just starting to get the hang of Flutter, but I\'m having trouble figuring out how to set the enabled state of a button.

From the docs, it says to set onP

Answer 1

For a specific and limited number of widgets, wrapping them in a widget IgnorePointer does exactly this: when its ignoring property is set to true, the sub-widget (actually, the entire subtree) is not clickable.

IgnorePointer(
    ignoring: true, // or false
    child: RaisedButton(
        onPressed: _logInWithFacebook,
        child: Text("Facebook sign-in"),
        ),
),

Otherwise, if you intend to disable an entire subtree, look into AbsorbPointer().
