Showing dialog from inside another dialog

How do you show a dialog from an already open dialog? Basically, nesting dialogs in Flutter.

When I try to use showDialog(); in Flutter from inside an already created dialog(for example, by clicking some link inside a dialog, another dialog should open on top of that dialog) I get the following lint error:

Flutter showDialog Lint Error

Does any one have any idea on how to solve this problem?

Solution

  • Nesting dialogs is VERY possible. You are facing an entirely different issue.

    Right now, you have conflicting imports from the custom_alert_dialog package, and the material.dart.

    To resolve the issue, you have to name one of the imports using the as keyword.

    E.x

    import 'dart:math' as math;

    Then to use it:

    // BEFORE 
final valueOfPi = pi;

// AFTER
final valueOfPi = math.pi

    The syntax of everything remains the same, but whenever you want to use an object or type from the library, just add the keyword as a prefix.
