Why do you use double.INFINITY in flutter?

by

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.
