When your loading of data is complete you have to call following code:

Navigator.pop(context);

Note: You should add return in front of showDialog for await to work.

Edit: If you are calling showDialog inside button press event, you can try following code:

showDialog();
await updateDetails();
Navigator.pop(context);

This will pop your dialog once update is complete.
