I am getting an error cannot find symbol

Is there something I have to add or import to get this to work?
Multidex support for Android 5. dex files and compiles them into a single . oat file for execution by the Android device. Therefore, if your minSdkVersion is 21 or higher multidex is enabled by default, and you do not need the multidex library. For more information on the Android 5.0 runtime, read ART and Dalvik.
dex file can have 65,536 methods(references) so if the number of references exceeds 65,536, you go with multidex.
Android 5.0 (API level 21) and higher uses ART which supports multidexing. Therefore, if your minSdkVersion is 21 or higher, the multidex support library is not needed.
Therefore, if your minSdkVersion is 21 or higher multidex is enabled by default, and you do not need the multidex library. For more information on the Android 5.0 runtime, read ART and Dalvik . Note: When running your app using Android Studio, the build is optimized for the target devices you deploy to.
How to Enable Multidex for Android App 1 Keeping a tap on the number of methods, the third party libraries added to the once project 2 Removing unused dependencies. 3 Avoiding the addition of group dependencies. More ...
Follow the below steps to enable multidex for the flutter project. Enable multidex. Open project/app/build.gradle and add the following lines. Enable Jetifier. Open project/ android / app /gradle.properties and add the following lines.
You may try using --multi-dex option. To solve this error, you can optimize your code or enable Multidex support in your Android project. You can avoid muiltidex support in your Android app by reducing the number of reference methods, as well as other libraries (dependencies).
For those who get cannot find symbol error, the following is stated in the official android developer documents:
If your minSdkVersion is 21 or higher multidex is enabled by default, and you do not need the multidex support library.
If you are using RN > 0.60 and androidx support, you may add,
import androidx.multidex.MultiDex;
