Android Application crash after the modification of this tool

[SoTasIt]

Hi, this project is quite awesome!
I have tried some android app built with flutter, but they just crashed without any log tagged with "reflutter" after I modified them using this tool. Surely I have use uber-apk-signer mentioned in the guide to align and sign the apk.

Here are some apps using flutter I found in github to test this tool, do I make something wrong about the usage of this tool?

Thanks for your time to read this!
