KeyframesSpecConfig

<init>

KeyframesSpecConfig()

KeyframesSpecConfig stores a mutable configuration of the key frames, including durationMillis, delayMillis, and all the key frames. Each key frame defines what the animation value should be at a particular time. Once the key frames are fully configured, the KeyframesSpecConfig can be used to create a KeyframesSpec.

import androidx.compose.animation.core.KeyframesSpec

KeyframesSpec(
    KeyframesSpec.KeyframesSpecConfig<Float>().apply {
        0f at 0 // ms  // Optional
        0.4f at 75 // ms
        0.4f at 225 // ms
        0f at 375 // ms  // Optional
        durationMillis = 375
    }
)

at

infix fun T.at(@IntRange(0) timeStamp: Int): KeyframesSpec.KeyframeEntity<T>

Adds a keyframe so that animation value will be this at time: timeStamp. For example: 0.8f at 150 // ms

with

infix fun KeyframesSpec.KeyframeEntity<T>.with(easing: Easing): Unit

Adds an Easing for the interval started with the just provided timestamp. For example: 0f at 50 with LinearEasing

import androidx.compose.animation.core.keyframes

// Use FastOutSlowInEasing for the interval from 0 to 50 ms, and LinearOutSlowInEasing for the
// time between 50 and 100ms
keyframes<Float> {
    durationMillis = 100
    0f at 0 with FastOutSlowInEasing
    1.5f at 50 with LinearOutSlowInEasing
    1f at 100
}

delayMillis

var delayMillis: Int

The amount of time that the animation should be delayed. Defaults to 0.

durationMillis

var durationMillis: Int

Duration of the animation in milliseconds. Defaults to DefaultDurationMillis
