Mastering Kotlin

Using Fragment KTX

Let's now explore the Fragment KTX module, which contains utility functions for working with fragments. First, we'll define our new dependency constant:

object Android {    ...    object Ktx {        const val core = "androidx.core:core-ktx:1.0.1"        const val fragment = "androidx.fragment:fragment-ktx:1.0.0"    }}

Now, we'll update app/build.gradle.kts:

dependencies {    ...    implementation(Deps.Android.Ktx.core)    implementation(Deps.Android.Ktx.fragment)}

Once the dependency is added, we can define FragmentTransactions using the commit() extension function like this:

supportFragmentManager.commit {    addToBackStack("fragment name")    add(SampleFragment(), "tag")    setCustomAnimations(R.anim.abc_fade_in, R.anim.abc_fade_out)}

This makes the addition ...
