# isInfinite property Null safety

Returns true if either component is double.infinity, and false if both are finite (or negative infinity, or NaN).

This is different than comparing for equality with an instance that has
*both* components set to double.infinity.

See also:

- isFinite, which is true if both components are finite (and not NaN).

## Implementation

`bool get isInfinite => _dx >= double.infinity || _dy >= double.infinity;`
