# react-native-progress-steps

A simple and fully customizable React Native component that implements a progress stepper UI. 
* Each steps content is displayed inside of a customizable ScrollView. 
* Fully customizable buttons are displayed at the bottom of the component to move between steps.

## Installation

If using yarn:

```
yarn add react-native-progress-steps
```

If using npm:

```
npm i react-native-progress-steps
```

## Usage

```
import { ProgressSteps, ProgressStep } from 'react-native-progress-steps';
```

Simply place a `<ProgressStep />` tag for each desired step within the `<ProgressSteps />` wrapper.

```
<View style={{flex: 1}}>
    <ProgressSteps>
        <ProgressStep label="First Step">
            <View style={{ alignItems: 'center' }}>
                <Text>This is the content within step 1!</Text>
            </View>
        </ProgressStep>
        <ProgressStep label="Second Step">
            <View style={{ alignItems: 'center' }}>
                <Text>This is the content within step 2!</Text>
            </View>
        </ProgressStep>
        <ProgressStep label="Third Step">
            <View style={{ alignItems: 'center' }}>
                <Text>This is the content within step 3!</Text>
            </View>
        </ProgressStep>
    </ProgressSteps>
</View>
```

### Button Styling Usage
Button container and text are fully customizable using the `nextBtnStyle, nextBtnTextStyle, previousBtnStyle, and previousBtnTextStyle` props.

Example usage to change a buttons text color: 

```
const buttonTextStyle = {
    color: '#393939'
};

return (
    <View style={{flex: 1}}>
        <ProgressSteps>
            <ProgressStep label="First Step" nextBtnTextStyle={buttonTextStyle} previousBtnTextStyle={buttonTextStyle}>
                <View style={{ alignItems: 'center' }}>
                    <Text>This is the content within step 1!</Text>
                </View>
            </ProgressStep>
            <ProgressStep label="Second Step" nextBtnTextStyle={buttonTextStyle} previousBtnTextStyle={buttonTextStyle}>
                <View style={{ alignItems: 'center' }}>
                    <Text>This is the content within step 2!</Text>
                </View>
            </ProgressStep>
        </ProgressSteps>
    </View>
)
```

### Current Step Error and Validation Handling
The `errors` prop should be used if there's a need for validation and error handling when clicking the next button. If you would like to prevent the next step from being rendered, set the `errors` prop to `true`. By default, it will be `false`.

Example usage of validation check:

```
state = {
    isValid: false,
    errors: false
};

onNextStep = () => {
    if (!this.state.isValid) {
      this.setState({ errors: true });
    } else {
      this.setState({ errors: false });
    }
};

render() {
    return (
      <View style={{ flex: 1 }}>
        <ProgressSteps>
          <ProgressStep label="First Step" onNext={this.onNextStep} errors={this.state.errors}>
            <View style={{ alignItems: 'center' }}>
              <Text>This is the content within step 1!</Text>
            </View>
          </ProgressStep>
          <ProgressStep label="Second Step">
            <View style={{ alignItems: 'center' }}>
              <Text>This is the content within step 2!</Text>
            </View>
          </ProgressStep>
        </ProgressSteps>
      </View>
    );
}

```
