react-native-pull-ups

Native Bottom Sheet Implementations for iOS and Android. Toddler approved ©

• iOS: built using FittedSheets. Credit for this module goes to this guy!
• Android: built using Material design's bottom sheet via BottomSheetBehavior.

Installation

npm install react-native-pull-ups

You'll need to update your Podfile to be targeting at least iOS 11.

platform :ios, '11.0'

Lastly, install the Pods to install iOS dependencies.

npx pod-install

Usage

Overview

• The sheet can be in one of three different states:
  • expanded: The sheet is fully expanded, and all content is visible.
  • collapsed: The sheet is visible, but only partially. This is defined by collapsedHeight, and is optional.
  • hidden: The sheet is out of view. Bring it into view by setting the state programmatically. To prevent users from hiding the view, set hideable={false}.
• The intrinsic height of the content placed in the sheet represents the height of the expanded state.
• When the sheet state is changed, the onStateChanged(newState: 'expanded' | 'collapsed' | 'hidden') event is fired. Generally, you will want to synchronize the state of your component with the value passed here.
• The sheet can be presented in two modes: persistent and modal.

Importing

Import the component from react-native-pull-ups:

import PullUp from 'react-native-pull-ups';

Persistent mode

A persistent PullUp is rendered within a parent container. It is always rendered inline, which means that the sheet cannot be expanded outside of the parent view. The background view is able to receive touch events at all times.

<View style={{ flex: 1 }}>
  { backgroundContent }
  <PullUp
    state={state}
    collapsedHeight={120}
    onStateChanged={(newState) => setState(newState)}
  >
    { sheetContent }
  </PullUp>
</View>

Note: Content rendered in a persistent sheet is mounted even when the sheet is hidden. This means that your component state will be persisted. If you prefer the content be re-mounted every time, conditionally render its children.

Modal mode

A modal PullUp can be rendered anywhere, just like the React-Native Modal. When presented in this manner, the background becomes dimmed and cannot receive touch events. To dismiss the modal, swipe the sheet down, tap the overlay, or press the back button. Alternatively, set dismissable={false} to only allow the modal to be closed programmatically through state="hidden".

  <PullUp
    modal
    state={state}
    onStateChanged={(newState) => setState(newState)}
  >
    { sheetContent }
  </PullUp>

Note: Content rendered in a modal sheet is only mounted when the sheet is expanded. This means that your component state will not be persisted.

Reference

Props

state

The current state of the sheet.

Type	Required
SheetState: "hidden" | "collapsed" | "expanded"	Yes

collapsedHeight

Enables the collapsed state by defining a height in px. This value determines how much of the sheet's content is visible when collapsed.

Type	Required
number	No

maxSheetWidth

The maximum width of the sheet. Generally used for visual appeal on larger screens.

Type	Required
number	No

modal

Enables modal mode. If false, the persistent inline mode is used.

Type	Default
bool	false

hideable

Allows the user to hide the sheet by swiping/dragging down. Note that the sheet can always be hidden by setting state to hidden, regardless of this value.

Type	Default
bool	true

dismissable

(Modal mode only): whether the modal can be dismissed by the user. If false, the modal can only be dismissed by setting state to hidden.

Type	Default
bool	true

tapToDismissModal

(Modal mode only): whether the modal can be dismissed by tapping the background overlay.

Type	Default
bool	true

useSafeArea

Automatically applies additional bottom padding to the sheet, if applicable.

Type	Default	Platform
bool	true	iOS

onStateChanged

Called when the sheet state is changed.

Type	Required
(newState: SheetState) => void	No

overlayColor

(Modal mode only): the color to use for the background overlay.

Type	Default
Color	"black"

overlayOpacity

(Modal mode only): the opacity to apply to the background overlay, ranging from 0.0-1.0.

Type	Default
number	0.5

iosStyling

A configuration object for customizing various FittedSheets styling options.

Type	Required	Platform
object	No	iOS

Object structure:

Key	Type	Default
pullBarHeight	number	24
presentingViewCornerRadius	number	20
shouldExtendBackground	bool	true
useFullScreenMode	bool	false
shrinkPresentingViewController	bool	false
gripSize	{ width: number, height: number }	{ width: 50, height: 6 }
gripColor	Color	#DDDDDD
cornerRadius	number	0
minimumSpaceAbovePullBar	number	0
pullBarBackgroundColor	Color	rgba(0,0,0,0)
treatPullBarAsClear	bool	false
allowPullingPastMaxHeight	bool	false
contentBackgroundColor	Color	rgba(0,0,0,0)

Note: By default, cornerRadius and contentBackgroundColor are not used. Instead, visually identical styles are applied via style for a more consistent and familiar behavior. See the style prop for more information. We leave these exposed because altering other styling options may require them to be tweaked to prevent visual bugs.

style

Styles to apply to the sheet content container.

Type	Required
ViewStyle	No

Default styles:

Platform	Default style
Android	{ flex: 1, backgroundColor: 'white' }
iOS	{ flex: 1, backgroundColor: 'white', borderTopRightRadius: 20, borderTopLeftRadius: 20 }
