Flutter_form_builder: Upgrading Form Builder from ^3.14.1 to ^4... > errors in Cloud FireStore & "AndroidX incompatibilities in a plugin"

[mgav]

Important: I'm a novice

**Everything works fine with Form Builder ^3.14.1

When upgrading to ^4.0.2, this is the error message:**

`FAILURE: Build failed with an exception.

Also, when I add cloud_firestore: ^0.14.4 to pubspec.yaml, this is the revised error message:

`FAILURE: Build failed with an exception.

I'm only working in Android for now, so this error shouldn't matter

Had the same and resolved it with:

adding

        buildToolsVersion = "29.0.3"
        compileSdkVersion = 29

to the defaultConfig of my apps build.gradle and changing

        classpath 'com.android.tools.build:gradle:4.1.0'

in my projects build.gradle

I also changed

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

in my gradle-wrapper.properties file

@akreienbring gives good advice.

@mgav The example app code and configuration were recently updated (#620), and it demonstrates that a clean Android build is possible:

https://github.com/danvick/flutter_form_builder/commit/c2b63433778187cd9258499f1bf5f53781fa3ffa#diff-50d858e0985ecc7f60418aaf0cc5ab587f42c2570a884095a9e8ccacd0f6545c

These versions are not the only working combination, but these were the latest release versions, and they work.

Closing since this issue duplicates #613.

Thank you so much @awhitford and @akreienbring!
