Pop snackbar

[thegioiso]

We had fluent.showSnackbar(); to show up a snackbar. And i see that every snackbar will stack on other. Can i have a function likefluent.popCurrentSnackbar() to pop it before we call show a new one?

If found this in the documentation of showSnackbar:

To dismiss the snackbar manually, use the following code:

final result = showSnackbar(context, snackbar);
result.remove();

Is this what you are looking for?

EDIT:
To avoid an error when the Snackbar already got dismissed automatically, wrap the call of remove() in an try-catch-block like so: #630 (reply in thread).

This is not what i need here, because it will cause error if the snack has dismissed.
Example:
We call a snack bar and its will auto dissmiss after 5s.
Before 5s, we can manually dismiss by this method.
But, after 5s, if we call this method, an error will occur:

══╡ EXCEPTION CAUGHT BY GESTURE ╞═══════════════════════════════════════════════════════════════════
The following assertion was thrown while handling a gesture:

When the exception was thrown, this was the stack:

So... Maybe i will need another way....

Thank you so much for your support.

Finally, i put this method in try catch block, everything works just... fine...

 try {
        _currentSnackBar.remove();
        // ignore: empty_catches
      } catch (e) {}
      /// go show new snackbarrrrr

Nice. Maybe I'll need this, too, some time.

I updated my answer accordingly.
