react-animated

For some reason I'm not able to see what I'm doing wrong with my code. I seem to be using Animated just as the documentation shows but this error keeps coming. The code snippet: import React, { Component } from 'react'; import { StyleSheet, Image, Animated, } from 'react-native' import Header from './../components/Header' export default class DrawerShell extends Component { constructor(props) { super(props) this.state = { showNav: false, } this.anim = new Animated.Value(0) this.openDrawer = this.openDrawer.bind(this) } openDrawer() { let toValue this.setState({ showNav: !this.state.showNav })

I want 2 views which transform like a circle with no rotation at the same time. The first view starts at the top and the second view at the bottom. I already asked how to do it with one view. I dont get it run with two views. Question Before //import liraries import React, { Component } from 'react'; import { View, Text, StyleSheet, Animated, Button, TouchableOpacity } from 'react-native'; // create a component export default class App extends Component { constructor() { super() this.animated = new Animated.Value(0); this.animated2 = new Animated.Value(0); var range = 1, snapshot = 50, radius

I have a ScrollView inside an animated View that has panning. <Animated.View {...this.panResponder.panHandlers}> <ScrollView> ... </ScrollView> <Animated.View> This is a sample view of my screen: A user should be able to swipe upwards and the draggable area should snap upwards, as shown below: Now my problem is the Scrollview. I want a user to be able to scroll the content inside. After the user has finished viewing the content inside and scrolls all the way up(by performing downward swiping motion) and tries to swipe further, the draggable area should move downwards to its original position.

I see many mobile apps having a feature that user can draw a square to indicate something to tag on the image. I'm building Face Tagging app and basically user draws square on the boundary of human's face on the image . I've Googled it many times but I'm not sure RN has some feature library for tagging. How can I achieve this? Is there any good library to draw square on image? And it will be even better if I can remember its coordinate width, height, and position of the rectangle. Any idea or suggestion will be highly appreciated! This is an example below You can use React Native ART library
