Answer 1

You probably has installed some dependencies using a package manager and some with other.

Check if you have package-lock.json and yarn.lock or another similar file from other package manager. Keep just the one from what you're using (yarn, npm, pnpm...) and remove all others.

Then run the command to install everything from package.json (ex. npm install or just yarn). This will make sure all dependencies listed at package.json has been installed with the same package manager.

Remember, if you kept yarn.lock so run yarn if you kept package-lock.json then run npm install.

After it just start your application as usual, and the error should be gone.

This React Native Screen version is not compatible with React Native 0.72 or higher.

To resolve this issue, follow these steps:

Open your project's build.gradle file at the project level. Add the following line inside the buildscript block, which defines the Kotlin version:

classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")

Make sure your buildscript block looks something like this:

buildscript {
    ext {
        // ... other configurations ...
        kotlinVersion = "1.8.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:7.0.0")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")
        // ... other dependencies ...
    }
}

By adding this line, you specify the Kotlin version for your project.

Sync your Gradle project to apply these changes. This should resolve the compatibility issue with React Native 0.72+ for your React Native Screen version.
