icu_kit 0.2.0

Internationalization for Flutter and Dart on Unicode's ICU4X. Numbers, dates, plurals, lists, collation, segmentation, bidi, IDNA — same output on every platform, including web.

Changelog

0.2.0

The number pipeline gains the full ECMA-402 formatting surface.

• Engine updated — web: re-run flutter pub run icu_kit:setup --force web (native updates itself)
• Added the complete ECMA-402 digit surface to format() — minimum/maximum fraction and integer digits, plus minimum/maximum significant digits — on all three engines.
• Added IcuCompactFormat for compact notation (1.2M) on all three engines.
• Added signDisplay, roundingMode, roundingIncrement, and trailingZeroDisplay across number, currency, percent, and unit formatting.
• Added currencyDisplay: "code" and explicit useGrouping control to the currency, percent, and unit facades.
• Added IcuPluralRules.categoryOfDecimal for operand-exact plural selection (trailing-zero aware).

0.1.0

First release — full ECMA-402 / Unicode internationalization for Dart and Flutter on all six platforms.

• API: one Dart API for number, currency, percent, and unit formatting (as strings or typed formatToParts parts); plural rules; dates and times across 17 calendars; time zones; relative time; lists; collation; display names; segmentation; case mapping; normalization; bidi; Unicode properties; exemplar characters; and IDNA. No Flutter dependency.
• Engines: native via dart:ffi (the build hook compiles icu_capi from the vendored ICU4X source); web via a bundled WebAssembly build of that engine (19 MB, or a 2.1 MB lean variant, 0.6 MB gzipped, via dart run icu_kit:setup --lean); or the browser's built-in Intl with no ICU4X download (IcuKit.init(webEngine: WebEngine.browserIntl)).
• Data: CLDR ships bundled, or loads lazily per-locale (bundleCldrData: false + IcuData.lazy) for a lean binary. slice cuts per-locale data by facade family (68 KB to 5.6 MB). One binary serves bundled and lazy data without a flag — see example_lean/.
• Vendoring: ICU4X 2.2.0 as a fork submodule carrying icu_kit's patches on a named branch.
