Unable to start activity ComponentInfo{.../com.plaid.internal.LinkRedirectActivity}

[boomney]

I am using Andriod Studio to build flutter app using this plugin. The link flow initialises as expected in the Emulator and I am redirected to the Bank (Monzo UK) but on completion and when the screen shows "All done", I am not redirected back to myapp, the emulator crashes - and I get the following messages:

Sorry, I figured it out, needed to change/add 'Theme.AppCompat' to AndriodManifest.

@boomney I am getting this error, on which activity did you add Theme.AppCompat? Thanks in advanced.

Edit: I found some info here https://github.com/plaid/plaid-link-android/issues/148
