No imploding/exploding animation in iOS

[PurnimaNaik]

The clusters just appear, its as if there is no animation. I am testing this out in iOS simulator and iOS device. I am assuming that react-native-maps-super-cluster comes with the spring animation out of the box. (Similar to the demo gif in README) All I have to do is add animateClusters={true}. Please correct me if I am wrong. @39otrebla @leolusoli

{(this.state.initialPosition!=null && this.state.arr.length > 0)?
  <ClusteredMapView
    provider={PROVIDER_GOOGLE}
    animateClusters={true}
    style={styles.mapContainer}
    data={this.state.clusterDataArray}
    renderMarker={this.renderMarker}
    renderCluster={this.renderCluster}
    initialRegion={this.state.initialPosition}
    ref={(element) => { this.mapRef = element }}
    showsUserLocation = {true}
    showsMyLocationButton={false}
    customMapStyle={CustomMapStyle}
    loadingEnabled={true}
    rotateEnabled={true}
    onRegionChangeComplete={this.onRegionChangeComplete}
    >
  </ClusteredMapView>
:
null}

  renderCluster = (cluster, onPress) => {
    const pointCount = cluster.pointCount,
          coordinate = cluster.coordinate,
          clusterId = cluster.clusterId

    return (
      <MapView.Marker 
          coordinate={coordinate} 
          onPress={onPress} 
          animateClusters={true}>
        <View style={styles.clusterContainer}>
          <Text style={styles.clusterText}>
            {pointCount}
          </Text>
        </View>
      </MapView.Marker>
    )
  }

  renderMarker = (arrData) => {
    return (
      <MapView.Marker
        image={require('../../icons/blue-marker-pin.png')}
        identifier={(arrData.id).toString()}
        key={(arrData.id).toString()}
        coordinate={arrData.location}
        />
    )
  }

Tried layoutAnimationConf too

  <ClusteredMapView
    animateClusters={true}
    **layoutAnimationConf={LayoutAnimation.Presets.spring}**
    provider={PROVIDER_GOOGLE}
    style={styles.mapContainer}
    data={this.state.clusterDataArray}
    renderMarker={this.renderMarker}
    renderCluster={this.renderCluster}
    initialRegion={this.state.initialPosition}
    ref={(element) => { this.mapRef = element }}
    showsUserLocation = {true}
    showsMyLocationButton={false}
    customMapStyle={CustomMapStyle}
    loadingEnabled={true}
    rotateEnabled={true}
    >

If I use LayoutAnimation.configureNext(LayoutAnimation.Presets.spring); in renderClusters(), every component other than the clusters & markers reacts to it i.e. the spring animation applies to every component except the clusters & markers.

I cut it down to a bare-bone ClusteredMapView-

  <ClusteredMapView
    data={this.state.clusterDataArray}
    animateClusters={true}
    renderMarker={this.renderMarker}
    renderCluster={this.renderCluster}
    initialRegion={this.state.initialPosition}
    ref={(element) => { this.mapRef = element }}
    >
  </ClusteredMapView>

This makes a fadeout effect not spring

:+1: I'm currently fighting this myself as well. There are no animations happening.

We are planning to migrate from LayoutAnimation to Animated library. This will give to developers more control on animations, as well as fix the all-or-nothing behavior of LayoutAnimation.

@39otrebla is this happening in the next few years or?

[vavdoshka]

anyone has an idea why this animation works on iOS built-in maps but not with PROVIDER_GOOGLE ?

[39otrebla]

We apologize for being unresponsive for so much time. We now have a major refactoring in progress to re-align with the latest React standards (like functional components & hooks). We'll try to include this as well.
