m method
M coordinate as num at index
.
Returns zero if M is not available when an index
>= 0 and < length.
m represents a value on a linear referencing system (like time). Could be associated with a 2D point (x, y, m) or a 3D point (x, y, z, m).
Throws RangeError if index
is out of bounds.
Implementation
@override
num m(int index) => this[index].m;
