Properties
- dimensions → Dimensions
-
The dimensions of the unit, e.g. length, time, mass.
finalinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- implicitOrigin → QuantityOrigin?
-
The origin that a QuantityPoint in this unit is implicitly relative to,
or
nullfor a unit measured from absolute zero.no setterinherited - plural → String
-
The plural name of the unit, e.g. "metres", "seconds".
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- safePlural → String
-
The plural name of the unit, wrapped in square brackets if it is not a NamedUnit.
no setterinherited
- safeSingular → String
-
The singular name of the unit, wrapped in square brackets if it is not a NamedUnit.
no setterinherited
- safeSymbol → String
-
The symbol of the unit, wrapped in square brackets if it is not a NamedUnit.
no setterinherited
- scale → num
-
The ratio of the unit to the base unit in SI-MKS.
finalinherited
- singular → String
-
The singular name of the unit, e.g. "metre", "second".
finalinherited
- spaceBeforeSymbol → bool
-
Whether to put a space before the symbol when displaying it.
finalinherited
- symbol → String
-
The symbol of the unit, e.g. "m" for metre, "s" for second.
finalinherited
- symbolForQuantity → String
-
The symbol of the unit, or an empty string if the unit is the dimensionless unit "one".
no setterinherited
- symbolWithSpace → String
-
The symbol of the unit, potentially prepended with a space based on spaceBeforeSymbol.

inherited
-
inverse(
) → Unit -
An inverted copy of this unit, inverting both the dimensions and scale.
inherited
-
named(
{required String symbol, required String singular, required String plural, bool? spaceBeforeSymbol}) → NamedUnit -
Creates a copy of this DerivedUnit as a NamedUnit with the given
symbol,singularandpluralnames. -
nameForValue(
num value) → String -
The appropriate name of the unit for the given
value, either singular or plural.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited

Operators
-
operator *(
Unit other) → Unit -
Multiplies this unit by
other, creating a new DerivedUnit.inherited -
operator /(
Unit other) → Unit -
Divides this unit by
other, creating a new DerivedUnit.inherited -
operator ==(
Object other) → bool -
Whether this unit is equal to
other, having the same scale and dimensions.inherited -
operator ^(
num exponent) → Unit -
Raises this unit to the power of
exponent, creating a new DerivedUnit.inherited
