Added #

• Centered dialog now closes on outside tap (barrier dismiss) like bottom sheet.
• Close button added to header (Material-style trailing X) in both bottom sheet and dialog.

Changed #

• Header layout unified via _buildModalHeader for consistent UX across presentations.

Docs #

• No README changes required (uses MaterialLocalizations.closeButtonLabel for i18n of Close tooltip).

QA #

• Ran dart format, flutter analyze, and flutter test — all green.

Changelog #

Added #

• Centered dialog presentation for the picker via new enum CountryPickerModalPresentation.
• New modalPresentation parameter for both constructor and Builder API.
• Example app updated with two demos (direct usage and builder) showcasing centered dialog.

Debug #

• Added debugPrint indicating which presentation style is used when opening the picker.

Docs #

• README updated with modalPresentation usage and API tables.

QA #

• Ran dart format, flutter analyze, and flutter test — all green.

Refactor (no functional changes) #

• Extracted repeated logic for suggested countries into _getSuggestedCodes() in CountryPicker state.
• Extracted modal header (drag handle, title, search field) into _buildModalHeader(...) and reused in _showCountryPicker().
• Reduced duplication, improved readability; public API and behavior unchanged.

QA #

• Ran dart format and flutter analyze — all green.

Changed #

• UI: labelText is now rendered above the country picker when provided.

Fixed/Perf #

• Removed an unused _searchController listener. Search updates are handled via TextField.onChanged inside the modal. Fewer redundant setState calls and more stable rebuilds.

Docs #

• README: synchronized version mentions (2.8.1) and minor copy edits.

QA #

• Ran dart format, flutter analyze, and flutter test — all green.
