const LENGTH = 10;
export default function App() {
  const [index, setIndex] = React.useState<number>(0);

  const increaseIndex = () => {
    setIndex(Math.min(index + 1, LENGTH - 1));
  };
  const decreaseIndex = () => {
    setIndex(Math.max(index - 1, 0));
  };

  return (
    <View style={styles.container}>
      <TouchableOpacity
        style={{ borderWidth: 1, marginTop: 20, backgroundColor: 'white' }}

Api Reference

DotConfig Interface

export interface DotConfig {
  size: number;
  opacity: number;
  color: string;
  margin: number;
  borderWidth?: number;
  borderColor?: string;
}

DecreasingDot Interface

export interface DecreasingDot {
  quantity: number;
  config: DotConfig;
}

Props

Prop	Type	Required(Default Value)	Description
length	number	required	Length of the list you want to associate with the carousel dots
currentIndex	number	required	Current index of the list.
maxIndicators	number	required	This number represents how many indicators you want to show, without decreasing size. Counting inactive indicators and the active indicator
activeIndicatorConfig	DotConfig	required	This is an object with the configuration of the active indicator
inactiveIndicatorConfig	DotConfig	required	This is an object with the configuration of the inactive indicator
decreasingDots	DecreasingDot[]	required	This is a list where you have to define the quantiy per element and the dot config. The quantity represents how many dots with this config you want per side (simetrically). The size of this elements should be decreasing size if you want this to look nice.
verticalOrientation	boolean	false	If you want this oriented vertically or horizontally. Default is horizontally
interpolateOpacityAndColor	boolean	true	Default is true. With this setted to true you will be able to see an animation everytime the activeDot change.

react-native-animated-dots-carousel's Issues

Add A feature to increase only width of active dot

decreasingDots does not work correctly with dynamic data

I'm using react-native-animated-dots-carousel and set the config:
length: 8; maxIndicator: 5;
when I set currentIndex = 0 for render for the first time the decreasingDots worked correctly.

But if I update the length = 7; currentIndex = 6, it will render wrong

expectation:

maxIndicators Property Prevents Rendering in "react-native-animated-dots-carousel"

Hello,

I am currently utilizing the "react-native-animated-dots-carousel" in my React Native project and have stumbled upon an issue with the maxIndicators property.

Description of the Issue:

When the number of items in the data array exceeds the value set in the maxIndicators property, the dots fail to render. Conversely, when the maxIndicators property is set to a value greater than the number of items, it functions correctly.
Steps to Reproduce:

1. Set the maxIndicators property to 3.
2. Include 4 items in the data array.
3. Observe that the dots does not render.

Expected Behavior:

I anticipated that setting a maxIndicators value less than the number of items would still allow the dots to function properly, with the additional items being accommodated.

Actual Behavior:

The dots fails to render when the maxIndicators value is less than the number of items in the data array.
Additional Information:

I find this behavior strange because, based on the examples provided in your GitHub repository, it seems like this functionality should work correctly. It appears that in your examples, the dots renders fine even when the maxIndicators is less than the number of items.
Environment:

1. React Native version: 0.71.1
2. OS : iOS

I would appreciate any guidance or updates that can address this issue. Thank you for your time and assistance.

Dots centered

Hey @felire , how i can always center dots, maybe you can help me with it?
Initially they not center:

I need something like that:

Add duration as prop

I think this is a pretty simple change, but could you add the animation duration to go from one dot to the next as a prop? In the code it looks like it's 300ms, and from my experience with it, it feels a little slow and 200ms would probably make it feel more like instagram and other apps.

Thanks.
