Android Studio – Could not get unknown property 'FLIPPER_VERSION' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler

This is the error I am getting while I’m trying to get an app to debug on the android emulator from android studio on visual studio code :

Could not get unknown property ‘FLIPPER_VERSION’ for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

What went wrong was:

  • What went wrong:
    A problem occurred evaluating project ‘:app’.
    Could not get unknown property ‘FLIPPER_VERSION’ for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Where? :

Build file ‘C:UsersdmdplOneDriveDesktopcitas3androidappbuild.gradle’ line: 270

This is what is along the line 270 on app.build.gradle:

debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
    exclude group:'com.facebook.fbjni'
}

    ${FLIPPER_VERSION} is meant to act as a placeholder for whatever the latest version is of the library

    Replace

    debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}")

    with

    debugImplementation("com.facebook.flipper:flipper:0.156.0")

    ensure you have your gradle.properties file in your android/ folder, if that file exists you should already see the version of FLIPPER defined in there already.

    I had this error while I was trying to move my project to another computer, the gradle.properties file was not included, so I had to copy it manually to the new computer.

    Then, all I needed to do, was to open the app on my Android studio and ran: Sync project with gradle files.
