Black screen appears during PlaidLink.open

[gilescm]

Hi, firstly thanks for this plugin! I am a developer at GoHenry, we've been using plaid_flutter for a long time now and it works great.

We have found a minor issue on Android devices. A temporary black screen always appears during the initial load of the plaid webview flow. In the project we have used plaid_flutter versions 2.2.2 and then recently 3.1.1. The black screen issue occurs in both, the attached video is using v3.1.1 and Google Pixel 5 with Android 13. Is it possible to look into this? I'm expect this is probably a platform quirk that can't be avoided but raising this issue anyway in case it is something that the plaid sdk has control over.

This has also been found on Samsung, Galaxy S10, Android 12.

Hi @gilescm, the issue is probably more related to the Plaid SDK itself than plugin. Sill I'll take a look into it 👍

Either way it's useful to have this issue reported here so we can keep track of it.
