!TIP

• My info: https://github.com/kietpt2003
• Due to some TypeScript issues that lead to unable to suggest code correctly.
• But we have try our best, so now if you using our sub path (Example: '/utils', '/themes'), you must initialize the import first, for the auto suggestion.

  export default MyComponent

Colors

We provide a variety of palete colors and some shadows!

Usage

  import  { colors } from '@kietpt2003/react-native-core-ui/themes';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    container: {
      flex: 1,
      backgroundColor: colors.black,
    },
  });

We provide variety of fontSize that aldready scaled by our scaleFont API

Usage

  import  { fontSize } from '@kietpt2003/react-native-core-ui/themes';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    text: {
      fontSize: fontSize._16,
    },
  });

Scaling Function

  import { scale, verticalScale, moderateScale } from '@kietpt2003/react-native-core-ui/utils';
  import  { colors, fontSize } from '@kietpt2003/react-native-core-ui/themes'

  const Component = props =>
    <View style={{
      width: scale(30),
      height: verticalScale(50),
      padding: moderateScale(5)
    }}>
      <Text style={{
        fontSize: fontSize._16,
        color: colors.black
      }}>Component</Text>
    </View>;

scale(size: number)

Will return a linear scaled result of the provided size, based on your device's screen width.

Usage

  import  { scale } from '@kietpt2003/react-native-core-ui/utils';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    container: {
      padding: scale(5),
    },
  });

scaleH(size: number)

Will return a linear scaled result of the provided size, based on your device's screen height.

Usage

  import  { scaleH } from '@kietpt2003/react-native-core-ui/utils';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    container: {
      position: 'absolute',
      top: scaleH(5),
    },
  });

moderateScale(size: number, factor?: number)

Sometimes you don't want to scale everything in a linear manner, that's where moderateScale comes in.
The cool thing about it is that you can control the resize factor (default is 0.5).
If normal scale will increase your size by +2X, moderateScale will only increase it by +X, for example:
➡️   scale(10) = 20
➡️   moderateScale(10) = 15
➡️   moderateScale(10, 0.1) = 11

Usage

  import  { moderateScale } from '@kietpt2003/react-native-core-ui/utils';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    container: {
      padding: moderateScale(5),
    },
  });

moderateHeightScale(size: number, factor?: number)

Same as moderateScale, but using scaleH instead of scale.

Usage

  import  { moderateHeightScale } from '@kietpt2003/react-native-core-ui/utils';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    container: {
      padding: moderateHeightScale(5),
    },
  });

scaleFont(size: number)

Will return a linear scaled result of the provided size, based on PixelRatio & scaleAvg. You can use fontSize from /theme instead of using scalefont().

Usage

  import  { scaleFont } from '@kietpt2003/react-native-core-ui/utils';
  import { StyleSheet } from 'react-native';

  const styles = StyleSheet.create({
    text: {
      fontSize: scaleFont(16), // fontSize._16
    },
  });

IPHONE_12_WIDTH
