Allow to await for the dialog show

[Fabio Biola]

Problem statement
I use the progress dialog to keep the user informed of a blocking operation.
So the progress dialog must be showed and hidden after an operation, but if the operation is async but terminates very quickly, the dialog is not hidden, because the showDialog method (used internally in the .show()) does not have finished showing the dialog.

Describe the solution you'd like
I would like to be allow to await the .show() method, like this

ProgressDialog dialog = ...; 
await dialog.show();

// do some work ...

await dialog.hide();

good idea, but call funciton require async.

Yeah sure, it is the main point of doing it.
Obviously you could also use the .then() method and chaining the Futures, but I think it is more readable this way.

Until this issue is resolved, you can use
await Future.delayed(Duration(seconds: 1));
for allowing the dialog to pop up

Could we get a new release with the fixed version?

By the way (for the impatient), a workaround until then:

pubspec.yaml

dependencies:
  progress_dialog:
    git: https://github.com/fayaz07/progress_dialog.git
