[Guide] to run the `/example` project with Flutter 3.19.1

[dJani97]

I got some gradle-related errors when trying to run the project with Flutter 3.19.1 on Android, here is how to fix them:

In the android/build.gradle file, change the android build tools dependency to:

classpath 'com.android.tools.build:gradle:7.4.1'

In the android/gradle/wrapper/gradle-wrapper.properties file, change the distributionUrl to:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip

Please include these in a future release.
