Android studio + kotlin compilation error

Question

I was modifying my app and when I ran it again, it threw me a big error, I don't think it's my code because my code doesn't have errors, but I think it's an error due to dependencies (I hope) but I better ask so as not to spoil the application and that the problem is even bigger This is the error it throws:

> Task :app:mergeDexDebug
AGPBI: {"kind":"error","text":"Cannot fit requested classes in a single dex file (# methods: 66078 > 65536)","sources":[{}],"tool":"D8"}
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: 
The number of method references in a .dex file cannot exceed 64K.

You need to multidex your application as you are over the 64K limit.

Here's how to add it:

In app level build.gradle:

android {
    defaultConfig {
        ...
        multiDexEnabled true
    }
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}
