Dialog not being hid after dispose() being called

[jjosenaldo]

My code is roughly the following:

await progressDialog.show(); // (1)
await callExternalApi(); // (2)
await progressDialog.hide(); // (3) 

Between (2) and (3), the ProgressDialog dismissed by back button log was shown, but the callExternalApi does nothing but calling an external API (and, well, I did not press the back button). Besides, the dialog was not dismissed. It also involves a Provider, but I don't think that's relevant. I looked up the code of this lib, and noticed that the log is shown in the dispose method of the _BodyState class, but that method does not call Navigator.pop. As a temporary workaround, I'm doing the following:

await progressDialog.show(); 
await callExternalApi(); 
if(progressDialog.isShowing()) {
    await progressDialog.hide();
} else{
    Navigator.pop(dialogContext);
}

but it is far from ideal. I have no idea why the dispose method of _BodyState was called.
