@vishuk570 (use -source 8 or higher to enable method references)
This suggest that Java JDK version you are using should be same or higher than 8.
Check your java version by using java -version in terminal.

if its already greater than 8, then I found one workaround. But this is just a workaround and I am yet to find final solution.

1. Locate the build.gradle file for the react-native-keychain module. It should be located at node_modules/react-native-keychain/android/build.gradle.
2. In the build.gradle file, find the android section.
3. Inside the android section, add the following lines:

codecompileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}

4. This configuration sets the source compatibility and target compatibility to Java 8.
5. Save the build.gradle file.
6. Clean build using cd android and ./gradlew clean
7. Again run the app.
