Quick Answer
To check the Flutter intl package latest version in 2026, use the official intl package page on pub.dev. Do not copy a version number from a blog post into production without checking pub.dev first, because package versions change.
Terminalflutter pub outdated intl flutter pub upgrade intl
What the intl Package Does
The Dart intl package supports locale-aware formatting and message handling:
- Date and time formatting
- Number and currency formatting
- Message lookup
- Plural and gender-aware messages
- Locale data initialization
In Flutter apps, intl is commonly used alongside ARB files and Flutter's gen-l10n tooling.
Safe Upgrade Checklist
- Check the latest version on pub.dev.
- Read the changelog for breaking changes.
- Run
flutter pub outdated intl. - Update
pubspec.yaml. - Regenerate localization files.
- Run widget tests for every supported locale.
- Manually test dates, currencies, plurals, and right-to-left languages.
Example pubspec Entry
YAML1dependencies: 2 flutter: 3 sdk: flutter 4 flutter_localizations: 5 sdk: flutter 6 intl: ^latest-compatible-version
Replace latest-compatible-version with the current version from pub.dev that fits your Flutter SDK constraints.
Common Upgrade Issues
| Issue | Fix |
|---|---|
| Version solving fails | Check Flutter SDK constraints and dependency conflicts |
| Generated localization code changes | Regenerate with flutter gen-l10n and review diffs |
| Date formatting breaks in tests | Initialize locale data before formatting |
| Plurals display incorrectly | Verify ARB plural syntax and CLDR category coverage |
Frequently Asked Questions
Where do I find the Flutter intl latest version?
Use the official pub.dev package page for intl. Package indexes are the source of truth for current versions, compatibility, changelog, and install commands.
Is intl required for Flutter localization?
Flutter localization workflows commonly use intl for formatting messages, dates, numbers, and currencies. The exact setup depends on whether you use Flutter's built-in gen-l10n workflow or another i18n package.
Should I always upgrade intl immediately?
Not automatically. Upgrade when you need a fix, compatibility update, or new behavior, then run locale-specific tests. Localization regressions often show up in dates, plurals, and generated message code.
What is the Flutter intl package used for?
The Flutter intl package provides locale-aware formatting and message handling for Dart and Flutter apps. It covers date and time formatting, number and currency formatting, message lookup, plural and gender-aware messages, and locale data initialization. In most Flutter projects it works alongside ARB files and the gen-l10n tooling to power generated, type-safe localizations.
How do I check the latest Flutter intl package version?
Run flutter pub outdated intl in your project to compare your pinned version against the latest resolvable one, or open the official intl page on pub.dev. Always confirm the version on pub.dev rather than copying a number from a blog post, because published versions and Flutter SDK compatibility constraints change over time.
Does the intl version need to match my Flutter SDK?
Yes, the intl version must satisfy your Flutter SDK and dependency constraints, which is why flutter pub upgrade intl may not jump straight to the newest release. If version solving fails, check your SDK constraints and conflicting packages, then pick the latest version that resolves cleanly before regenerating localization code.
