Error in gradle

[franquicidad]

Hello thanks for the library but it has a compile error with implementation 'com.craftman.cardform:cardform:0.0.2'

I realised the library works well with gradle 3.4.0. I got into similar trouble when I updated to 5.1.
This is how mine looks.
classpath 'com.android.tools.build:gradle:3.4.0'
