  )

  renderHeader = () => (
    /* render */
  )

  render() {
    return (
      <View style={styles.container}>
        <BottomSheet
          snapPoints = {[450, 300, 0]}
          renderContent = {this.renderContent}

        />
    </View>)
  }
}

Props

name required default description
snapPoints yes E.g. [300, 200, 0]. Points for snapping of bottom sheet coomponent. They define distance from bottom of the screen. Might be number or percent (as string e.g. '20%') for points or percents of screen height from bottom. Note: Array values must be in descending order.
initialSnap no 0 Determines initial snap point of bottom sheet. The value is the index from snapPoints.
renderContent no Method for rendering scrollable content of bottom sheet.
renderHeader no Method for rendering non-scrollable header of bottom sheet.
enabledGestureInteraction no true Defines if bottom sheet could be scrollable by gesture.
enabledHeaderGestureInteraction no true Defines if bottom sheet header could be scrollable by gesture.
enabledContentGestureInteraction no true Defines if bottom sheet content could be scrollable by gesture.
enabledContentTapInteraction no true Defines whether bottom sheet content could be tapped.
enabledManualSnapping no true If false blocks snapping using snapTo method.
enabledBottomClamp no false If true block movement is clamped from bottom to minimal snapPoint.
enabledBottomInitialAnimation no false If true sheet will grows up from bottom to initial snapPoint.
enabledInnerScrolling no true Defines whether it’s possible to scroll inner content of bottom sheet.
callbackNode no reanimated node which holds position of bottom sheet, where 0 it the highest snap point and 1 is the lowest.
contentPosition no reanimated node which holds position of bottom sheet’s content (in dp)
headerPosition no reanimated node which holds position of bottom sheet’s header (in dp)
overdragResistanceFactor no 0 `Defines how violently sheet has to stopped while overdragging. 0 means no overdrag
springConfig no { } Overrides config for spring animation
innerGestureHandlerRefs no Refs for gesture handlers used for building bottom sheet. The array consists fo three refs. The first for PanGH used for inner content scrolling. The second for PanGH used for header. The third for TapGH used for stopping scrolling the content.
simultaneousHandlers no Accepts a react ref object or an array of refs to handler components.
onOpenStart no Accepts a function to be called when the bottom sheet starts to open.
onOpenEnd no Accepts a function to be called when the bottom sheet is almost fully openned.
onCloseStart no Accepts a function to be called when the bottom sheet starts to close.
onCloseEnd no Accepts a function to be called when the bottom sheet is almost closing.
callbackThreshold no 0.01 Accepts a float value from 0 to 1 indicating the percentage (of the gesture movement) when the callbacks are gonna be called.
borderRadius no Border radius of content wrapper (excluding header)

Methods

snapTo(index)

Imperative method on for snapping to snap point in given index. E.g.

// Snap to the snap point at index 0 (e.g. 450 in [450, 300, 0])
this.bottomSheetRef.current.snapTo(0)

Here this.bottomSheetRef refers to the ref passed to the BottomSheet component.

Example

More complex examples can be found in the Example folder. To view the examples in the Expo app, open a Terminal and run:

yarn
cd Example
yarn
expo start

The example app is also available on Expo.

Todo

It’s not finished and some work has to be done yet.

  1. Play with magic config values
  2. Horizontal mode
  3. Deal with GH in inner scrollView
  4. Cleanup code (e.g. measuring of components)

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
