fix the end extend of actions in dismiss animation

[miDeb]

The end extend of secondary actions must be smaller, since their position is not at the same point as the primary action (ie. the Offset zero).

before:

after:

A workaround would be to wrap the ListTile with a Container and set a color.

Hi @miDeb , thanks for this PR.
This is strange, I cannot reproduce the before use case with the current source code. But I think you're right, the end extent should be different for each actions.
Under which Flutter version are you?
Can you paste here the complete sample please, so that I can reproduce and understand before I merge this?

Oh I think I know why. This is because I have a white background in my tiles and it's transparent in your case
