extensions

This project is a starting point to build useful widget extensions for most used widgets such as padding and containers to minimize UI codes

Publishing

🎖 Installation

dependencies:
  extensions: "^0.0.2"

Import

import 'package:flutter_extension_kits/flutter_extension_kits.dart';

Usage For Widgets

Text('Line 01').paddingAll(8);
Text('Line 02').paddingOnly(left : 2, top : 4, right : 6, bottom : 8 );
Text('Line 03').paddingSymmetric(horizontal : 10, vertical : 20);

Usage For Variables

int

millisecondsToDate

print(1601996400000.millisecondsToDate()); // DateTime(2020, 10, 7)

double

roundWithDigit

const value1 = 10.45678;
print(value1.roundWithDigit(1));   // 10.5
print(value1.roundWithDigit(2));   // 10.46
print(value1.roundWithDigit(3));   // 10.457
print(value1.roundWithDigit(0));   // 10.45678
print(value1.roundWithDigit(-1));  // 10.45678

const value2 = 10.434321;
print(value2.roundWithDigit(1));   // 10.4
print(value2.roundWithDigit(2);    // 10.43
print(value2.roundWithDigit(3));   // 10.434

num

commaFormat

print(100.commaFormat());         // '100'
print(1000.commaFormat());        // '1,000'
print(1000000.commaFormat());     // '1,000,000'
print(1000000.123.commaFormat()); // '1,000,000.123'

String

format

const String text = 'Today is {1} and tomorrow is {0}';
final List<String> placeHolders = List<String>()
  ..add('Tuesday')
  ..add('Monday');

final String finalString = text.format(placeHolders);
//'Today is Monday and tomorrow is Tuesday';

toDate

print('20201008'.toDate());       // DateTime(2020, 10, 8)

toInt

print('123'.toInt());             // 123

toDouble

print('123.4567'.toDouble());     // 123.4567

isNewLine

print('\n'.isNewLine());          // true
print('test'.isNewLine());        // false

Date

formatString

final date = DateTime(2020, 10, 7);
print(date.formatString());                     // '10.07 2020'
print(date.formatString(format: 'yyyy/MM/dd')); // '2020/10/07'

diffDays, diffHours, diffMinutes, diffSeconds

final dateA = DateTime(2020, 10, 7, 20, 10, 30);
final dateB = DateTime(2020, 8, 2, 10, 5, 10);
final dateC = DateTime(2020, 10, 7, 20, 10, 30);

// dateA - dateB
print(dateA.diffDays(dateB));       // 66
print(dateA.diffHours(dateB));      // 1594
print(dateA.diffMinutes(dateB));    // 95645
print(dateA.diffSeconds(dateB));    // 5738720
