You are getting this error because you've reached (and went over) the limit of the android build architecture - a single DEX file can hold only around 64 thousand references.

To fix this issue you have two options:

Use multi-dex - this means instead of having just one DEX file, you will have multiple dex files in your APK. You can follow this tutorial to set it in your build files. This might affect your min SDK version.
Use Proguard or R8 - among other features, these tools provide code shrinking. This means all of the code that is not used will be removed, and therefore the limit of 64k references should not be reached. You can follow this tutorial to set code shrinking up.

in your android\app\build.gradle add multiDexEnabled true to the defaultConfig. And add the following : dependencies { implementation 'com.android.support:multidex:1.0.3' } Read more here: https://developer.android.com/studio/build/multidex — Richardd, Aug 06 '19 at 08:54
