measurement

Dart library for handling units and values

Installation

pub.dev/measurement

Usage

See

• test/unit_test.dart
• test/measurement_test.dart

Common utilities

DistanceConversion.convertValue(
    DistanceUnit.KILOMETRES, DistanceUnit.YARD, 1.34) // 1465.4374

Modelling distance and conversion

Distance distance = Distance(1.34, DistanceUnit.KILOMETRES);
distance.getValue(DistanceUnit.METRES); // 1340
distance.convert(DistanceUnit.METRES);  // Distance(1340, DistanceUnit.METRES)

Design

Default

To avoid confusion among developers, there is no default unit for a measurement. Unit must be consciously supplied. If unit is known before hand, to avoid calculation measurements can be standardized.

Functional programming

Conversions are as far as possible generated before hand, best during compilation. Functions are looked up with O(1) complexity.
