Gesture-handler

https://docs.expo.io/versions/latest/sdk/gesture-handler.html

is there everywhere a working example with EXPO?

https://github.com/kmagiera/react-native-gesture-handler/blob/master/Example/swipeable/index.js

what is this? i dosent use DangerZone? and its not really good explained…

Can someone help me. i want a flatlist wirh swipable rows.

The GitHub repo you linked to has examples. They’re not directly copy-and-pastable but they communicate the concepts behind the API. You can use Expo.DangerZone.GestureHandler to get access to the react-native-gesture-handler exports.

how can i import this in expo?

Normal:
import Swipeable from ‘react-native-gesture-handler/Swipeable’;

EXPO:
const Swipeable = Expo.DangerZone.GestureHandle.Swipeable;

I’ve got it working in production with Expo’s GestureHandler (Android, iOS awaiting review but worked when testing in production mode) using the following setup:

My SwipeableList (note that I use FlatList from RN directly, the GestureHandler FlatList did not work for me). Also I am passing the function to be called when on the rightAction pressed in with the itemArray data:

import React, { Component } from 'react';
import {
  FlatList,
  StyleSheet,
} from 'react-native';
import { DangerZone } from 'expo';
const { GestureHandler } = DangerZone;
const { RectButton } = GestureHandler;

const Row = ({ item }) =>
  <RectButton
    style={styles.rectButton}
    onPress={() => item.onPress()}
  >
    <BnListItem />
  </RectButton>;

const SwipeableRow = ({ item }) => {
  return (
    <BnSwipeableRow
      onDelete={item.onDelete}
    >
      <Row item={item} />
    </BnSwipeableRow>
  );
};

class BnSwipeableList extends Component {
  render() {
    return (
      <FlatList
        {...this.props}
        keyExtractor={(item, index) => index}
        renderItem={({ item, index }) =>
          <SwipeableRow item={item} index={index} />}
      />
    );
  }
}

export { BnSwipeableList };

My SwipeableRow component:

import React, { Component } from 'react';
import { Animated, StyleSheet, View } from 'react-native';
import { DangerZone } from 'expo';
import Icon from 'react-native-vector-icons/MaterialIcons';

import Swipeable from './Swipeable';

const { GestureHandler } = DangerZone;
const { RectButton } = GestureHandler;

const AnimatedIcon = Animated.createAnimatedComponent(Icon);

export default class BnSwipeableRow extends Component {
  updateRef = ref => {
    this._swipeableRow = ref;
  };

  close = () => {
    this._swipeableRow.close();
  };

  renderRightActions = (progress, dragX) => {
    const scale = dragX.interpolate({
      inputRange: [-80, 0],
      outputRange: [1, 0],
      extrapolate: 'clamp',
    });
    return (
      <View style={{ width: 90, flexDirection: 'row' }}>
        <RectButton
          style={styles.rightAction}
          onPress={() => {
            this.props.onDelete();
            this.close();
          }}
        >
          <AnimatedIcon
            name="delete-forever"
            size={30}
            color="#fff"
            style={[styles.actionIcon, { transform: [{ scale }] }]}
          />
        </RectButton>
      </View>
    );
  };

  render() {
    const { children } = this.props;
    return (
      <Swipeable
        ref={this.updateRef}
        friction={2}
        rightThreshold={40}
        renderRightActions={this.renderRightActions}
      >
        {children}
      </Swipeable>
    );
  }
}

const styles = StyleSheet.create({
  actionIcon: {
    width: 30,
    marginHorizontal: 10,
  },
  rightAction: {
    alignItems: 'flex-end',
    backgroundColor: '#dd2c00',
    flex: 1,
    justifyContent: 'center',
  },
});

And finally my rendition of the Swipeable component from GestureHandler:
Into this file I just copied the Swipeable component from the GestureHandler Repo and replaced all imports from react-native-gesture-handler with importing from Expo DangerZone:

import React, { Component } from 'react';
import { Animated, StyleSheet, View } from 'react-native';
import { DangerZone } from 'expo';

const { GestureHandler } = DangerZone;
const {
  PanGestureHandler,
  TapGestureHandler,
  State,
} = GestureHandler;

const DRAG_TOSS = 0.05;

export type PropType = {
  children: any,
  friction?: number,
  leftThreshold?: number,
  rightThreshold?: number,
  overshootLeft?: boolean,
  overshootRight?: boolean,
  onSwipeableLeftOpen?: Function,
  onSwipeableRightOpen?: Function,
  onSwipeableOpen?: Function,
  onSwipeableClose?: Function,
  renderLeftActions?: (
    progressAnimatedValue: any,
    dragAnimatedValue: any
  ) => any,
  renderRightActions?: (
    progressAnimatedValue: any,
    dragAnimatedValue: any
  ) => any,
  useNativeAnimations?: boolean,
};

export default class Swipeable extends Component {

FWIW I started this guide. Not finished but maybe it’ll help, maybe you can help update it!
