πŸ‘Ύ FlutterPlus

Creating apps using Flutter is great, but it can get better!

FlutterPlus is an open-source library created to make Flutter development faster, easier and more intuitive.

Create Containers, Buttons, TextFields, Texts and RichTexts customized with few lines.

Navigate between Screens, open BottomSheets, Dialogs and Snackbars without context anywhere in your code.

Use extensions to treat dates, strings, numbers and files.

Many of the solutions found here were created for my own use throughout my journey with Flutter.

I decided to bring everything together in a single place to help my work and that of anyone interested. ;)

I will always try to keep the documentation up to date but it may happen that I forget to put something or other here.

🍬 Demonstration

An appetizer of the real meaning of the library. Two codes that do the same thing, the first using the library and the second with native widgets.

A customized Container with centralized text that accepts user interaction.

FlutterPlus compare

πŸ”© Installation

Add the flutter_plus dependency to your project's pubspec.yaml file.

dependencies:
  flutter_plus: any

Import a single file to access all components.

import 'package:flutter_plus/flutter_plus.dart';

- This library will always be in constant evolution, so:

1- If you don't want to have problems with names or attributes changing and stopping, I suggest setting the version when you start using it.

2- If you're like me who likes evolution and don't mind a little rework when it is for the best, leave it without a fixed version and stay tuned for updates ;)

*No extra adjustments are required to work on iOS, Android, Web or Desktop.

πŸ“š Examples

The following are examples of how to use and configure the main features of the library.

*You can also find an example project showing how to use the library here.

πŸ›  Widgets

The Widgets below are evolutions of the native Flutter. They were created to increase productivity and facilitate customization, with more powerful and intuitive attributes.

Create more complex widgets with less code.

πŸ“Œ ContainerPlus

For me, the Container widget is the basis of Flutter. Our ContainerPlus is an evolution of the native, easier to customize and with several properties.

Example 1:

ContainerPlus(
  width: 150,
  height: 150,
  radius: RadiusPlus.all(20),
  color: Colors.yellow,
  shadows: [
    ShadowPlus(
      color: Colors.red,
      moveDown: -10,
      moveRight: -10,
      blur: 5,
      spread: 1,
      opacity: 0.2,
    ),
    ShadowPlus(
      color: Colors.blue,
      moveDown: 10,
      moveRight: 10,
      blur: 10,
      spread: 5,
      opacity: 0.5,
    ),
  ],
  border: BorderPlus(
    color: Colors.black,
    width: 2,
  ),
  child: TextPlus(
    'EXAMPLE 1',
    isCenter: true,
    color: Colors.white,
  ),
);

Example 2:

  gradient: GradientPlus.linear(
    colors: [
      Colors.yellow,
      Colors.orange,
      Colors.pink,
    ],
    begin: Alignment.topLeft,
    end: Alignment.centerRight,
  ),
  innerShadows: [
    InnerShadowPlus(
      color: Colors.green,
      blur: 10,
    )
  ],
  child: TextPlus(
    'EXAMPLE 2',
    isCenter: true,
    color: Colors.white,
  ),
);

Example 3:

bool isLoading = false;

ContainerPlus(
  margin: EdgeInsets.only(top: 48),
  width: 150,
  height: 150,
  color: Colors.black,
  radius: RadiusPlus.only(topLeft: 40, bottomRight: 10),
  skeleton: SkeletonPlus.automatic(enabled: this.isLoading),
  onTap: () {
    setState(() {
      this.isLoading = !this.isLoading;
    });
    Future.delayed(Duration(seconds: 5), () {
      setState(() {
        this.isLoading = !this.isLoading;
      });
    });
  },

πŸ”§ Utils

In addition to the standard widgets we have some abstractions that will save you code and time so you can focus on what really matters to your project.

πŸ“Œ NavigatorPlus

NavigatorPlus makes it possible to navigate between screens from anywhere in your code, without the need for a context.

You need to configure it to work.

β€’ Navigate to the next screen:

// Navigate to desired screen
navigatorPlus.show(NextScreen());
// Open desired screen as modal
navigatorPlus.showModal(NextScreen());

β€’ Back or close screen:

// Back or close to previous screen
navigatorPlus.back();
// Check if there is a previous screen to go back
if (navigatorPlus.canBack) {
  navigatorPlus.back();
}
// Back to first stack screen
navigatorPlus.backAll();

β€’ Return data to source screen:

// Call the next screen with await waiting for a return
var result = await navigatorPlus.show(NextScreen());

// Return to the previous screen passing the desired data
navigatorPlus.back(result: customData);

β€’ Configuration:

Recommended: Replace MaterialApp with FlutterAppPlus.

return FlutterAppPlus(
  title: 'Flutter Plus Example',
  home: HomeScreen(),
);

Alternative: Add the keys of the navigatorPlus and snackBarPlus.

MaterialApp(
  title: 'Flutter Plus Example',
  navigatorKey: navigatorPlus.key,
  builder: (context, child) {
    return Scaffold(
      key: snackBarPlus.scaffoldKey,
      body: child,
    );
  },
);

	    await launch(url);
	  } else {
	    throw 'Could not launch $url';
	  }
	},
);
