"content": "# React Native Pulse Animation\n\n\n\n## Installation\n\n```\n npm install react-native-pulse --save\n```\n\n## Usage\n\n```js\nconst Pulse = require('react-native-pulse').default;\n\nclass helloWorld extends Component {\n render() {\n return (\n \n \n \n );\n } \n}\n\n```\n\n## Props\n\nComponent accepts several self-descriptive properties:\n\n\n- **`color`** _(String)_ - Backgroundcolor for pulse. React-native colors supported. Default color is blue.\n- **`diameter`** _(Number)_ - This is the maximum diameter that a pulse will be. Defaults to 400.\n- **`duration`** _(Number)_ - Duration in milliseconds this is the delay new pulses will be created. Defaults to 1000.\n- **`image`** _(Object)_ - Image for center pulse thumbnail.\n- **`initialDiameter`** _(Number)_ - The diameter new pulses will start with. Defaults to 0.\n- **`numPulses`** _(Number)_ - This is the number of pulses that will be rendered. Defaults to 3.\n- **`pulseStyle`** _(Object)_ - Style properties for pulses (borderColor eg.)\n- **`speed`** _(Number)_ - Speed in milliseconds pulse will redraw. Defaults to 10.\n- **`style`** _(Object)_ - Style properties for pulse container (positioning eg.)\n"
