In Flutter, you can use the double.INFINITY
constant to represent an infinitely large number. This can be useful in a few different situations:
- When you want to set the maximum or minimum size of a widget, you can use
double.INFINITY
to indicate that the widget should be as large as possible. For example:
Container( width: double.INFINITY, height: double.INFINITY, child: Text('Hello World'), )
When you want to set the maximum or minimum value of a range, you can use double.INFINITY
to indicate that the range should have no upper or lower bounds. For example:
Slider( min: 0, max: double.INFINITY, value: 50, onChanged: (value) { print(value); }, )
When you want to set the maximum or minimum value of a double
variable, you can use double.INFINITY
to indicate that the value should be as large or small as possible. For example:
double minValue = double.INFINITY; double maxValue = double.INFINITY; List<double> values = [1, 2, 3, 4, 5]; for (double value in values) { minValue = min(minValue, value); maxValue = max(maxValue, value); } print('Min value: $minValue'); print('Max value: $maxValue');
Overall, double.INFINITY
can be useful in Flutter when you want to represent an infinitely large number or when you want to set a maximum or minimum value that has no bounds.
