Dependencies

This plugin depends on the SVG icons and main ring is an SVG icon as well, so necessary module should be installed along.

Inside the react native project do the following

• npm i react-native-ring-picker --save install the picker element
• npm i react-native-svg --save install the direct dependency of react native svg, since default icon is SVG and picker accepts the collection of SVG icons
• cd ios got to iOS project folder
  • pod install install native packages inside iOS project folder necessary for SVG work like RNSVG from ../node_modules/react-native-svg

Basic default UI

<ReactNativeRingPicker
    girthAngle={120}
    iconHideOnTheBackDuration={300}
    styleIconText={{fontWeight: 'bold'}}
/>

whereas in this example 5 default icons are used from the react-native-ring-picker plugin itself.

Picker with custom icons with configurable ids and titles

<ReactNativeRingPicker
    icons={[{id: "custom_id_1", title: "custom title 1"}, <PaymentCard id={"payments"}/>, "action_3", <Search title={"find"} color={"#F88DFF"}/>, "action_5"]}
    girthAngle={120}
    iconHideOnTheBackDuration={300}
    onPress={(iconId) => someExternalIdSelection(iconId)}
    styleIconText={{fontWeight: "bold"}}
    style={{flex: 0, marginTop: 0}}/>
/>

where as in this example custom icons are sent into the picker. Picker accepts:

• either strings, which value would be converted into ids and title
• or objects with properties like id or title. If no id is passed - "default" will be used. If no title is passed id will be used.
• or react elements, basically any element can be used but I suggest SVG ones.

Picker with 3 custom icons and 90 girth angle.

<ReactNativeRingPicker
    icons={[<PaymentCard id={"payments"} title={"Your payments"}/>, {"id": "default", "title": "Default action"}, <Search title={"find"} color={"#F88DFF"}/>]}
    girthAngle={90}
    onPress={(iconId) => someExternalIdSelection(iconId)}
    showArrowHint={false}
/>

whereas in this example 3 custom icons are used:

• uses custom id and title
• {id, title} object uses custom id and title but default icon provided by the ring picker
• uses custom title and the component name is used as an id by default (search)
