A flutter package that provide basic utils like Themes and Error Handler Widget

A package that provide basic utils like Themes, common BuildContext extension and simple Error Page widget.

Great for creating lots of flutter apps as a portfolio.

Features

  • Tired of defining themes manually? just use the default ThemeData from this package:

    import 'package:core/core.dart' as core;
    
    class MyApp extends StatelessWidget {
      const MyApp({super.key});
    
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          title: core.appName,
          theme: core.AppThemes.light,
          darkTheme: core.AppThemes.dark,
          ...
        );
      }
    }
  • Need shorthand for the common use of context? Try the BuildContext extension from this package:

    import 'package:core/core.dart';
    
    class MyWidget extends StatelessWidget {
      const MyWidget({super.key});
    
      @override
      Widget build(BuildContext context) {
        // Shorthand for Theme.of(context)
        context.theme;
    
        // Shorthand for MediaQuery.of(context)
        context.mediaQuery;
    
        // Shorthand for Scaffold.of(context)
        context.scaffoldState;
    
        // Check "src/utils/extensions.dart" for more
    
        return Container();
      }
    }
  • Need a simple page to display error info? try ErrorPages from the package:

    import 'package:core/core.dart';
    
    // Will display status code 400 with 'Bad Request' text below it.
    ErrorPages.client.badRequest();
    
    // Will display status code 500 with 'Internal Server Error' text below it.
    ErrorPages.server.internalServerError();
    
    // Will display page based on requested status code.
    //
    // The Example below will display status code 404 with
    // 'Not Found' text below it.
    ErrorPages.byCode(404);
    
    // You can also add custom message to the page
    // (Default message is 'Sorry for the inconvenience').
    //
    // The message displayed below statusCode and name.
    ErrorPages.client.notFound(message: 'The Page You Requested Not Found');
    ErrorPages.byCode(403, message: 'You are not allowed to access this');
    
    // See preview below for page visual.

Getting started

  1. Add the package to your dependencies:

    dependencies:
      core:
        git:
          url: https://github.com/KeidsID/flutter_app_core_package.git
  2. Then, you just need to call init() once in main():

    import 'package:core/core.dart' as core;
    
    void main() {
      core.init();
      ...
    }

    You can also customize the Theme via init():

    import 'package:flutter/material.dart';
    import 'package:core/core.dart' as core;
    
    void main() {
      core.init(
        appName: 'My App Name',
        appPrimaryColor: Colors.amber,
        useMaterial3: true,
      );
      ...
    }

Now, you are ready to use this package’s utilities.

Usage

main.dart

import 'package:flutter/material.dart';
import 'package:core/core.dart' as core;

void main() {
  core.init(
    appName: 'Flutter Demo',
    useMaterial3: true,
  );

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: core.appName, // "Flutter Demo"
      // Both theme used material 3
      theme: core.AppThemes.light, 
      darkTheme: core.AppThemes.dark,
      themeMode: ThemeMode.system,
      // Simple page to display 404 Not Found
      home: core.ErrorPages.client.notFound(), 
    );
  }
}
