Steps to reproduce the behavior

When requesting for a test purchase instead of selecting 'Test card, always approves' try selecting 'Slow test card, approves after a few minutes.'.

Hey, I've just tested now and flutter seems to only send string as a parameter. I've release 2.0.0+12 for the fix. Please try and come back.

hey again @hyochan ! The issue seems to be fixed now. App is not crashing and I am getting the required Platform exception for acknowledgement of purchase.

Thanks again!

My pleasure!
