### buildFloatFloatMap

Artifact: [androidx.collection:collection](https://developer.android.com/jetpack/androidx/releases/collection) [View Source](https://cs.android.com/search?q=file:androidx/collection/FloatFloatMap.kt+function:buildFloatFloatMap) Added in [1.5.0](https://developer.android.com/jetpack/androidx/releases/collection#1.5.0)

```
public static final @NonNull FloatFloatMap buildFloatFloatMap(
    @NonNull Function1<@NonNull MutableFloatFloatMap, Unit> builderAction
)
```

Builds a new `https://developer.android.com/reference/androidx/collection/FloatFloatMap` by populating a `https://developer.android.com/reference/androidx/collection/MutableFloatFloatMap` using the given `https://developer.android.com/reference/androidx/collection/package-summary#buildFloatFloatMap(kotlin.Function1)`.

The instance passed as a receiver to the `https://developer.android.com/reference/androidx/collection/package-summary#buildFloatFloatMap(kotlin.Function1)` is valid only inside that function. Using it outside of the function produces an unspecified behavior.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull Function1<@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/collection/MutableFloatFloatMap, https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-unit/index.html> builderAction` | Lambda in which the `https://developer.android.com/reference/androidx/collection/MutableFloatFloatMap` can be populated. |
