DateTime.now().subtractYears(1);  // subtracts 1 year from the current date

List extension

final list = [1, 2, 3] << 4;  // [1, 2, 3, 4], appends 4 to the list using the `<<` operator
list.replaceFirstWhere(10, (item) => item == 2);  // true, replaces the first occurrence of 2 with 10
list.replaceLastWhere(20, (item) => item > 1);  // true, replaces the last item greater than 1 with 20

Navigation extension

context.to(MyPage());  // Navigates to `MyPage` using `to()`
context.toNamed('/home');  // Navigates to the named route '/home' using `toNamed()`
context.back();  // Pops the current route using `back()`
context.backUntil((route) => route.isFirst);  // Pops routes until the first one using `backUntil()`
context.toWithReplace(AnotherPage());  // Replaces current route with `AnotherPage` using `toWithReplace()`
context.replaceWithNamed('/dashboard');  // Replaces the current route with named route '/dashboard' using `replaceWithNamed()`
context.toAndRemoveAll(HomePage(), (route) => false);  // Navigates to `HomePage` and removes all previous routes using `toAndRemoveAll()`
context.toNamedAndRemoveAll('/login', (route) => false);  // Navigates to named route '/login' and removes all previous routes using `toNamedAndRemoveAll()`

Gesture extension

widget.onInkTap(() => 'Tapped!'.logMsg());  // Adds an ink splash effect with `onInkTap()`
widget.onTap(() => 'Tapped!'.logMsg());  // Adds a basic tap gesture with `onTap()`
widget.onDoubleTap(() => 'Double Tapped!'.logMsg());  // Adds a double-tap gesture with `onDoubleTap()`
widget.onTapCancel(() => 'Tap Cancelled!'.logMsg());  // Adds a tap cancel gesture with `onTapCancel()`

num.isBetween(value1, value2, {inclusive = false});  // Checks if [this] is between [value1] and [value2], inclusive if [inclusive] is true.
num.roundToDecimals(decimalPlaces);  // Rounds the number to [decimalPlaces] decimal places.
double.asRadians;  // Converts degrees to radians.
double.asDegrees;  // Converts radians to degrees.
T.maxim(upperBound, {exclusive = false});  // Limits the value to [upperBound], exclusive if [exclusive] is true.
T.minm(lowerBound, {exclusive = false});  // Ensures the value is not less than [lowerBound], exclusive if [exclusive] is true.
T.clampAtMin(lowerBound);  // Ensures the value is not below [lowerBound].
