JTextPlus
As we all know, text is a key component of any mobile app's user interface. and it is fustrating to use Text or RichText Widget to create attractive text.

style: const TextStyle(
fontSize: 25, color: Colors.white, letterSpacing: 1.5),
jTextStyles: rules2,
);
JMarquee
A Flutter widget that scrolls text infinitely. Provides many customizations including custom scroll directions, durations, curves as well as pauses after every round.
JMarquee(
maxHeight: 50,
scrollAxis: Axis.horizontal,
accelerationCurve: Curves.fastLinearToSlowEaseIn,
pauseAfterRound: 3.seconds,
blankSpace: 10,
velocity: 100,
child: const FlutterLogo(
size: 100, style: FlutterLogoStyle.horizontal),
),
JMarquee(
maxHeight: 50,
blankSpace: 50,
child: JTextPlus(
'<r>JMarquee</r> is a flutter widget that scrolls widget infinitely.',
jTextStyles: [JTextStyle('r', color: Colors.red)]),
)
RToast & RSnackBar
With RSnackBar and RToast it is now easier than ever to show a little notification to the user. It may appear on the screen in any direction, including the top, bottom, center, and so on.
- In the true sense of RToast & RSnackBar, you can call it whenever you need it, without any restrictions!
- Feature-rich, support for displaying notifications, text, loading, attachments, etc. RToast & RSnackBar
- Support for popping up various custom RToasts & RSnackBars, or you can pop up any Widget as long as it meets the requirements of the flutter code.
- API is simple and easy to use
- Pure flutter implementation
// RTost Demo
OutlinedButton(
onPressed: () => showRTost(context,
msg: '👋 Hi i am form top center.',
config: RToastConfig(alignment: Alignment.topCenter)),
child: const Text('TOP CENTER'),
);
// RSnackBar Demo
simpleTile('Simple Loading Snackbar',
onPressed: () =>
showRSnackBar(context, config: RSnackbarLoadingConfig('Loading')),
onDismissed: () => removeRSnackBar()),
DateTime APIs
Most popular datetime apis are:
DateTimeFormat
The user can choose from a variety of standard date and time formats as well as a particular customised pattern. Additionally, by using Datetimelang, the user can specify a local language, such as Hindi, Punjabi, Chines, etc.
Example
var now = DateTime.now();
// default code = 'en'(English)
var datedef = DateTimeFormat(now);
// code = 'hi'(Hindi)
var datehi = DateTimeFormat(now, lang: DateTimeLang.hi);
// 1st
print(datedef.yMMMEd());
print(datedef.yMMMEd(isFull: true));
// 2st
print(datehi.yMMMd());
print(datehi.yMMMd(isFull: true));

DateTimeLang
For more control over datetime language you may can create your own JSON file, load it into the datetimelang api, and then set it as a default language.
/// **Load file locally **
await DateTimeLang.loadFromFile(CODE: 'fr', path: 'lib/assets/fr.json');
/// **Load file form Url**
//
/// Under the hood, **English & Hindi** are already available.
///
/// Chinese (zh-CN): https://datetimelangs-default-rtdb.asia-southeast1.firebasedatabase.app/zh-CH.json
///
/// French (fr): https://datetimelangs-default-rtdb.asia-southeast1.firebasedatabase.app/fr.json
///
/// Afrikaans (af): https://datetimelangs-default-rtdb.asia-southeast1.firebasedatabase.app/af.json
await DateTimeLang.loadFromUrl(
CODE: 'zh-CH',
url:'https://datetimelangs-default-rtdb.asia-southeast1.firebasedatabase.app/zh-CH.json');
// Now that you have both languages, choose a default language.
DateTimeLang.setDefaultLang('zh-CH');
var now = DateTimeFormat(DateTime.now());
print(now.yMMMd(isFull: true));
// To make it straightforward and appealing, you can,
// however, directly access the format() function.
print(DateTime.now().format().yMMM());

Timeago
Timeago is a dart library that converts a date into a humanized text. Instead of showing a date 2020-12-12 18:30 with timeago you can display something like "now", "an hour ago", "~1y", etc. By default Timeago ONLY support 'en' and 'hi' code(language code).To add more of the supported languages use DateTimeLang class
var oldDateTime = DateTime(2012, 6, 10);
var t1 = Timeago.since(oldDateTime);
var t2 = Timeago.since(oldDateTime, code: 'hi');
// en
print(t1.format());
print(t1.format(isFull: true));
print(t1.format(isFull: true, yearFormat: (p0) => p0.yMMMEd()));
print(t1.format(isFull: true, yearFormat: (p0) => p0.yMMMEd(isFull: true)));
// hi
print(t2.format());
print(t2.format(isFull: true, yearFormat: (p0) => p0.yMMMEd()));
print(t2.format(isFull: true, yearFormat: (p0) => p0.yMMMEd(isFull: true)));
