⚡ Performance

• Performance improvements thanks to caching + minor code revision (3625045)

• Significant speedup of the convertFromTo extensions by caching the underlying property instances instead of rebuilding them on every call
• Numeral systems conversion is now faster: cached regular expressions and more efficient base conversion algorithms

Changelog

• Added Illuminance property (@denxorz)
• Added kilojoules (@lhengl)
• Fixed typos (@denxorz)
• Bump Dart constraints

• Added kilojoules (@lhengl)
• Fixed typos (@denxorz)
• Bump Dart constraints

Added 5 new properties: density, amount of substance, molar volume, molar mass and reciprocal of molar mass. Now it is also possible to define a compound unit in the form of a ratio (e.g. Density units are defined as the ratio between mass and volume).

Thanks to @Dokotela for his PRs!

• Improved Pascal-Bar conversion
• We forced the use of types. So that many more error will be caught at compile-time. E.g. ConversionNode has an associated type that is the type of the name (e.g. LENGTH, AREA, etc.)

• We finally introduce extensions on num and String. Checkout the documentation for more details. Now you can easily convert in this way:

1.convertFromTo(LENGTH.meters, LENGTH.inches)

• We also refactor a little bit the code: now all the properties inherit from CustomProperty, this change leads to a reduction of ~500 lines of code.

• We fixed a wrong conversion (energy foot pound)

Breaking:

• Node becomes ConversionNode
• SimpleCustomConversion becomes SimpleCustomProperty
• CustomConversion becomes CustomProperty

Improved the formatting of the string representation of the number (stringValue): now it is also possible to choose between decimal or scientific notation. Added feet (US survey), feet squared (US survey) and kilocalories.

Fix compatibility issue of 1.1.0 with the previous release.

Updated README.md.

Fix links in README.md.

In this release we added a complete CustomConversion definition. You are not anymore tied to SimpleCustomProperty! Check it out in the updated README. We also simplified all the code!

units_converter is stable since some releases. In this first 1.x version we made a huge work to improve the algorithm conversion. Now it is 2x faster then the previous one and it is simpler (less line of code with known algorithms). We added more test, the code coverage is now 100%. This release will not break anything, it is compatible with the previous one.

Added hectoPascal. Added a bunch of other test (99% code coverage). Minor bug fix (non-critical).

Breaking. In this release we used the lints package and changed enum to camelCase. We also added minutes/kilometer and energy foot pounds units.

Add support for null safety. Added some test. Added fluid ounces, gill, pennyweight, troy ounce. Bugfix.

Added mils.

Added Property class. It is the parent of all the properties. In this way we can also remove some code. Now you can assign a custom name to a Property object.

Fix force conversion. Fix some comment and README

Fix time typo and time symbols
