Length class

A length Measurement - for example 55.67 metres.

To create a new Length object, use any of this class's factory constructors. For example,

Length heightOfEverest = Length.fromKilometres(8.848);

Use one of the properties, such as inMetres, to retrieve the double value of the Length in the specified length unit. For example,

Length heightOfEverest = Length.fromKilometres(8.848);
assert(heightOfEverest.inMetres == 8848.0);

This class provides a collection of arithmetic and comparison operators.

See Measurement for the collection of arithmetic and comparison operators which this class provides.
