A button for React apps

# react-native-button
A button for React apps

# Usage

Install the button from npm with `npm install react-native-button --save`. Then, require it from your app's JavaScript files with `import Button from 'react-native-button'`.

```js
import React, { Component } from 'react';
import Button from 'react-native-button';

export default class ExampleComponent extends Component {
  constructor(props, context) {
    super(props, context);
  }
  _handlePress() {
    console.log('Pressed!');
  }
  render() {
    return (
      <Button
        style={{fontSize: 20, color: 'green'}}
        styleDisabled={{color: 'red'}}
        onPress={() => this._handlePress()}>
        Press Me!
      </Button>
    );
  }
};

```

The React packager will include the Button component in your app's JS package and make it available for your app to use.

## Disabled prop usage

You can control a button's state by setting `disabled` prop value in this way:

```js
import React, { Component } from 'react';
import Button from 'react-native-button';

export default class ExampleComponent extends Component {
  constructor(props, context) {
    super(props, context);
      this.state = {
        isDisabled: false
      }
    }
  _handlePress() {
    this.setState({
      isDisabled: true
    });
    console.log('Now, button disabled');
  }
  render() {
    const { isDisabled } = this.state;
    return (
      <Button
        style={{ fontSize: 20, color: 'white' }}
        styleDisabled={{ color: 'white' }}
        disabled={isDisabled}
        containerStyle={{ padding: 10, height: 45, overflow: 'hidden', borderRadius: 4, backgroundColor: 'aqua' }}
        disabledContainerStyle={{ backgroundColor: 'pink' }}
        onPress={() => this._handlePress()}
      >
        Press Me!
      </Button>
    );
  }
};

```
