请问一下pullrelease状态不显示是什么问题

[yourenA]

版本："react-native-pull": "latest",
`
async onPullRelease(resolve){
let that=this;
await that.getWeather(that.state.localCity);
console.log('刷新');
resolve();
}

topIndicatorRender=(pulling, pullok, pullrelease)=> {
    const hide = {position: 'absolute', left: 10000};
    const show = {position: 'relative', left: 0};
    setTimeout(() => {
        if (pulling) {
            this.txtPulling && this.txtPulling.setNativeProps({style: show});
            this.txtPullok && this.txtPullok.setNativeProps({style: hide});
            this.txtPullrelease && this.txtPullrelease.setNativeProps({style: hide});
        } else if (pullok) {
            this.txtPulling && this.txtPulling.setNativeProps({style: hide});
            this.txtPullok && this.txtPullok.setNativeProps({style: show});
            this.txtPullrelease && this.txtPullrelease.setNativeProps({style: hide});
        } else if (pullrelease) {
            this.txtPulling && this.txtPulling.setNativeProps({style: hide});
            this.txtPullok && this.txtPullok.setNativeProps({style: hide});
            this.txtPullrelease && this.txtPullrelease.setNativeProps({style: show});
        }
    }, 1);
    return (
        <View style={{flexDirection: 'row', justifyContent: 'center', alignItems: 'center', height: 60}}>
            <ActivityIndicator size="small" color="white" />
            <Text style={{color:'white'}} ref={(c) => {this.txtPulling = c;}}>下拉刷新</Text>
            <Text style={{color:'white'}} ref={(c) => {this.txtPullok = c;}}>松开刷新</Text>
            <Text style={{color:'white'}} ref={(c) => {this.txtPullrelease = c;}}>刷新中</Text>
        </View>
    );
}

<PullView style={{width: Dimensions.get('window').width}} onPullRelease={this.onPullRelease}
topIndicatorRender={this.topIndicatorRender} topIndicatorHeight={60}>

下拉的时候显示“下拉刷新”，
下拉到一定高度的时候显示“松开刷新”
可是松开的时候没有显示“刷新中”，而是直接隐藏刷新条
onPullRelease里的getWeather是请求
请问一下哪里出问题了？
