• Update to CLDR v42.

v0.18.0

• Add support for minimumSignificantDigits / maximumSignificantDigits in
  NumberFormat.
• Add support for plural in NumberFormat.compact() ('2 milliards').
• Fix negative number formatting / parsing in NumberFormat.compact().
• Add optional parameter to NumberFormat.compact() to explicitly add sign
  even for positive values.
• Add decimalPatternDigits to NumberFormat which supports specifying the
  number of decimal digits in a decimal pattern.
• Update to cldr 40.
• Migrate to package:lints/recommended.yaml.
• Remove some instances of dynamic types from the API.

v0.17.0

Compare Source

• Migrate to null safety.
• Add @pragma('vm:prefer-inline') to Intl methods that already have
  @pragma('dart2js:tryInline'), for the same reason: to help omit message
  descriptions from compiled output.
• Breaking Change [#​123][]: Fix parsing of two-digit years to match the
  documented behavior. Previously a two-digit year would be parsed to a value
  in the range [0, 99]. Now it is parsed relative to the current date,
  returning a value between 80 years in the past and 20 years in the future.
• Use package:clock to get the current date/time.
• Fix some more analysis complaints.
• Update documentation to indicate that time zone specifiers are not yet
  implemented [#​264][].

v0.16.1

Compare Source

• Add an analysis_options.yaml and fix or suppress all the complaints from it.
• Add unit tests using dart:ffi to compare formatting output to ICU.
• Bump SDK requirements up to 2.5.0 for dart:ffi availability.
• Attempt to compensate for erratic errors in DateTime creation better, and add
  tests for the compensation.
• Add a MessageFormat class. It can prepares strings for display to users,
  with optional arguments (variables/placeholders). Common data types will
  be formatted properly for the given locale. It handles both pluralization
  and gender. Think of it as "internationalization aware printf."
• Change plural behavior with floating point howMany argument so that doubles
  that are equal to integers print the same as the integer 1. That is, '1
  dollar', rather than '1.0 dollars'.
• Add package:intl/locale.dart that exports a standards-compliant Locale class.

v0.16.0

Compare Source

• Fix 'k' formatting (1 to 24 hours) which incorrectly showed 0 to 23.
• Tighten up types in a couple of places.
• Add dart2js pragmas for inlining to help remove descriptions and other
  compile-time information from the output.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pubspec.lock

Command failed: flutter pub upgrade intl
The lower bound of "sdk: '>=2.2.2 <3.0.0'" must be 2.12.0'
or higher to enable null safety.

The current Dart SDK (3.2.3) only supports null safety.
