responsive_flutter 0.0.4

responsive_flutter #

PRs Welcome

A Flutter package for scaling the size your apps UI and fontSize across different sized devices, insipired from react-native-size-matters and react-native-responsive-dimensions

Installation #

You just need to add responsive_flutter as a dependency in your pubspec.yaml file.

  responsive_flutter: ^0.0.4

Usage #

// Inside build function to pass context

  Widget build(BuildContext context) {
    return Container(
        width: ResponsiveFlutter.of(context).scale(120),
        height: ResponsiveFlutter.of(context).verticalScale(100),
        padding: EdgeInsets.all(ResponsiveFlutter.of(context).moderateScale(8)),
        child: Text("Responsive flutter",
            style: TextStyle(fontSize: ResponsiveFlutter.of(context).fontSize(3))));

Functions #

  • wp(double percentage)
    Will return the percentage of the screen's width.

    // Example 20% of screen's width
  • hp(double percentage)
    Will return the percentage of the screen's height.

    // Example 20% of screen's height
  • fontSize(double size)
    Will return fontSize that occupies exactly size% of the screen size.

  • scale(double size)
    Will return linear scaled result of the provided size, based on your device's screen width.

  • verticalScale(double size)
    Will return linear scaled result of the provided size, based on your device's screen height.

  • moderateScale(double size, [double factor]) Sometimes you don't want to scale everything in a linear manner, that's where moderate scale 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

[0.0.4] - Oct 2019.

  • Fixed issue where width and height equals to O.O on release.

[0.0.3] - July 2019.

  • Fixed type issue with moderateScale function.

[0.0.2] - June 2019.

  • Added wp(double size) and hp(double size) functions to get percentage of the screen's width/height.

[0.0.1] - June 2019.

  • Initial release.
