DoubleWatcherExtension extension

DoubleWatcherExtension

Extension on Watcher<double> to enable direct manipulation of double values. This extension provides convenient methods for handling double precision floating-point numbers within a ValueNotifier. It simplifies arithmetic and other operations on double values, such as rounding, scaling, or clamping, without the need to explicitly access the .value property.

Ideal for scenarios where reactive double values need to be manipulated frequently and with precision, this extension ensures more readable and concise code.

Example:

final doubleWatcher = 10.5.watcher;
doubleWatcher.increment(2.5); // Directly adds 2.5 to the value (now 13.0)
doubleWatcher.round(); // Directly rounds the value (now 13.0)
// These operations modify the double value within the ValueNotifier without accessing `.value`
