onPressed problems

[sigjak]

In version 1.1.0 the onPressed function seems to be running on build but not when pressed. In a ListView.builder with a simple function, which prints index of list when run, the index is printed for the entire list on build but not when the slidable is pressed.

I assumed a function should be called in onPressed but that is not the case. My misunderstanding. Maybe the readme could be more informative.

I had a similar problem trying to simply print. Trying to do so without a context argument raised the following error: Error: The argument type 'void Function()' can't be assigned to the parameter type 'void Function(BuildContext)?'. I found this behavior to be surprising. I did not expect it.

endActionPane: ActionPane(
  children: [
    SlidableAction(
      onPressed: () => print('hey'),
      label: 'Test',
    ),
  ],
  motion: ScrollMotion(),
),

To fix the error, you can pass context or really just some dummy throw away variable, like the underscore _, e.g.

endActionPane: ActionPane(
  children: [
    SlidableAction(
      onPressed: (_) => print('hey'),
      label: 'Test',
    ),
  ],
  motion: ScrollMotion(),
),
