The flutter_helper_utils is a valuable tool for developers who want to speed up their development process. It offers various extensions and helper methods that can make development more efficient.
Hey there! As developers, we all know that writing repeated or boilerplate code can really slow down the development process. That's why I wanted to share all the helper methods and extensions I've created in my previous projects within this package.
For instance, instead of calling MediaQuery.of(context); to get the MediaQuery of a specific context, this package makes it as easy as using context.mq;.
Or if you want to safeley cast dynamic list to list of strings you can use ConvertObject.tryToList<String>(dynamicList);
If you want to learn more about extensions, click here.
To use this package, add flutter_helper_utils as a dependency in your pubspec.yaml file:
dependencies:
flutter:
sdk: flutter
flutter_helper_utils: ^1.1.2Then, run flutter packages get in your terminal.
After installation, import the package in your dart file:
import 'package:flutter_helper_utils/flutter_helper_utils.dart';You can now use any of the helper methods or extensions provided by the package. Some examples include:
// Navigate to a new screen and remove all previous screens from the stack.
context.pushReplacementNamed('/home');
// Navigate to a new screen and remove it from the stack after it's closed.
context.pushNamedAndRemoveUntil('/login', ModalRoute.withName('/home'));
// Navigate to a new screen and pass/recieve data from/to it.
final data = await context.pushNamed<String?>('/details', arguments: {'id': 123});
// push, pushReplacement, popPage, popUntil and canPop are also available.// Get the MediaQuery of a specific context.
final mediaQuery = context.mq;
// Get the screen width, height, and size.
final screenWidth = context.widthPx;
final screenHeight = context.heightPx;
final screenHeight = context.sizePx;
// Check if the screen is in landscape mode.
final isLandscape = context.isLandscape;
// Check if the screen is in portrait mode.
final isPortrait = context.isPortrait;// Check the current platform using `Platform`.
final isMobile = Platform.isMobile;
final isIOS = Platform.isIOS;
final isAndroid = Platform.isAndroid;
final isDesktop = Platform.isDesktop;
// or using `BuildContext`.
final isMobile = context.isMobile;
final isIOS = context.isIOS;
final isAndroid = context.isAndroid;
final isDesktop = context.isDesktop;// Get the ThemeData of a specific context.
final theme = context.themeData;
// Get the accent color from the current theme.
final accentColor = context.themeData.accentColor;
// Get the text theme from the current theme.
final textTheme = context.textTheme;
// Get the running device system brightness.
final brightness = context.sysBrightness;
// Check if the current brightness is dark.
final brightness = context.isDark; // or `isLight`// check whether the string is a hex color or not;
bool isHex = '#FF0000'.isHexColor; // true;
// Get a color from a hexadecimal string
Color color = '#FF0000'.toColor;
// Get a hexadecimal string from Color
String hexadecimal = color.toHex(leadingHashSign: false); // FF0000// Parsing a string to DateTime using null safety
DateTime? dateTime = '2022-04-27'.tryToDateTime;
// Parsing a string to DateTime
DateTime dateTime2 = '2022-04-27'.toDateTime;
final now = DateTime.now();
// Adds 1 day to current date
DateTime tomorrow = now.addDays(1); // addHours also available
// Returns the day after current date
DateTime nextDay = now.nextDay;
// Returns true if the current date is yesterday
bool isYesterday = now.isYesterday; // false
// Returns true if the current date is today
bool isToday = now.isToday; // true
// Returns the previous month from the current date
DateTime previousMonth = now.previousMonth;
// Getting small month name from month number
String smallMonthName = now.month.toSmallMonthName; // e.g Mar
// Getting full month name from month number
String fullMonthName = now.month.toFullMonthName; // e.g Marchconst duration = Duration(hours: 1, minutes: 30);
// Adds the Duration to the current DateTime and returns a DateTime in the future.
DateTime futureDate = duration.fromNow;
// Subtracts the Duration from the current DateTime and returns a DateTime in the past
DateTime pastDate = duration.ago;
// run async delay
await duration.delay<void>();
final int number = 100;
// convert numbers to greeks.
// e.g 1000 => 1k
// 20000 => 20k
// 1000000 => 1M
String greeks = number.asGreeks; // 10k
// Easy way to make Durations from numbers.
Duration seconds = number.asSeconds; // Duration(seconds: 100)
int numberOfDigits = number.numberOfDigits; // 3
// Return this number time two (tripled, quadrupled, and squared are also available).
int doubled = number.doubled; // 200String text = 'hello there!';
// wrap string at the specified index
String wrappedString = text.wrapString(2);
// capitalize the first letter of the string
String capitalized = text.capitalizeFirstLetter; // 'Hello there!'
// convert the string to PascalCase ('camelCase' and 'Title Case' also available)
String pascalCase = text.toPascalCase; // 'HelloThere'.
// check if the string is alphanumeric
bool isAlphanumeric = text.isAlphanumeric; // false
// convert to one line string
String twoLineString = 'ab'
'cd';
String oneLine = text.toOneLine; // abcd
// check if the string is null or empty
bool isEmptyOrNull = text.isEmptyOrNull;
// check if the string is a valid username
