Your new users shouldn't jump in at the deep end. First give them a pleasurable, delightful introduction and only then let them explore your awesome app.

Getting everything running merely takes a minute. Don't believe me? Try it out!

## Examples

Try out the example [running in your browser](https://snack.expo.io/rk80s-CDz).

Also check out the three examples files: the [simple example](examples/Simple.js), the [example with a Call-to-Action button](examples/WithCTA.js) or the [example with custom button components](examples/CustomButtons.js).

## Required Properties

* `pages` (required): an array of pages in the following shape:
  * `backgroundColor` (required): a background color. The color of the font and dots adapts to the background color.
  * `image` (required): a component (e.g. `<Image />`) to display at the top of the page.
  * `title` (required): a string **OR** a React-Native component.
  * `subtitle` (required): a string **OR** a React-Native component.

## Optional Properties

### Buttons

* `nextLabel` (optional): a string **OR** a React-Native component for the Next label. Defaults to `Next`.
* `showNext` (optional): a bool flag indicating whether the Next button is visible. Defaults to `true`.
* `skipLabel` (optional): a string **OR** a React-Native component for the Skip label. Defaults to `Skip`.
* `showSkip` (optional): a bool flag indicating whether the Skip button is visible. Defaults to `true`.
* `onSkip` (optional): a callback that is fired if the Onboarding is skipped.
* `skipToPage` (optional): when pressing skip, go to that page (e.g. `skipToPage={2}`). If this prop is provided, ignores `onSkip`.
* `onDone` (optional): a callback that is fired after the Onboarding is completed.
* `showDone` (optional): a bool flag indicating whether the Done checkmark button is visible. Defaults to `true`.

### General

* `controlStatusBar` (optional): a bool flag indicating whether the status bar should change with the background color. Defaults to `true`.
* `flatlistProps` (optional): additional props for the [FlatList](https://facebook.github.io/react-native/docs/flatlist.html) which holds all the pages.
* `transitionAnimationDuration` (optional): The duration in milliseconds for the animation of the background color for the page transition. Defaults to `500`.
* `allowFontScaling` (optional): Font scaling can cause troubles with high-resolution screens. You may want to disable it. Defaults to `true`.
* `pageIndexCallback` (optional): a function that receives the page `index` as a parameter on page change. [Example Usage](https://github.com/jfilter/react-native-onboarding-swiper/pull/40)

### Default Page Styles

For the pages in the `pages` array, you can set the default styles (and override the styles set by this component).

* `containerStyles` (optional): override the default container styles.
* `imageContainerStyles` (optional): override the default image container styles e.g. the `paddingBottom` of 60.
* `titleStyles` (optional): override the default title styles.
* `subTitleStyles` (optional): override the default subtitle styles.

### Adjust Individual Page Styles

For each page in the `pages` array, you can override the default page styles. [An example](examples/CustomButtons.js).

* `titleStyles` (optional): modify styles of a specific page's title.
* `subTitleStyles` (optional): modify styles of a specific page's subtitle.

## Custom Components Properties

You can also provide your own custom components for the buttons and the dots. All of them have access to a `isLight` prop but it's up to you what you do with it. Also checkout [this example](examples/CustomButtons.js).

* `SkipButtonComponent` (optional): Skip Button, gets `skipLabel` as prop.
* `NextButtonComponent` (optional): Next Button, gets `nextLabel` as prop.
* `DoneButtonComponent` (optional): Done Button.
* `DotComponent` (optional): Dot for the pagination, gets `selected` as prop to indicate the active page.
