Dismissible : false issue

[ifasdev]

Dear ,

When we use dismissible : false in Slider button, the following issue comes

A dismissed Dismissible widget is still part of the tree.
The following assertion was thrown building Dismissible-[<'cancel'>](dirty, dependencies: [Directionality, _EffectiveTickerMode], state: _DismissibleState#49402(tickers: tracking 2 tickers)):
A dismissed Dismissible widget is still part of the tree.

Make sure to implement the onDismissed handler and to immediately remove the Dismissible widget from the application once that handler has fired.

The relevant error-causing widget was:
SliderButton SliderButton:file:///D:/Android/gppl_order_app/lib/screens/home.dart:97:38
When the exception was thrown, this was the stack:

I am getting the same issue, please release a fix for this, thank you :)

[am2074]

Got the same issue. Any updates?

[Aderiani]

I have the same issue

[IlyesYhy]

To solve this issue ctrl+click on the slider button widget and in your slider.dart file replace
key: Key("cancel")
by
key: UniqueKey()
in your Dismissible widget (L.~146)

This is due to the fact that your key isn't unique.

More infos here.

I have already fixed this issue, you can use the package from my GitHub repo

In pubspec.yaml:

  slider_button:
    git: "https://github.com/da-nish/Slider-Button"

[anirudhsharma392]

removed dismissible, Changed action to callback of type Future Function(), now u can return false to avoid the button to dismiss.
