Title

Fix RTL checkbox click area issue

Description

This PR fixes a critical issue with checkbox click areas in RTL (Right-to-Left) text direction mode. Previously, when using RTL text direction, checkboxes were visually positioned correctly on the right side but remained clickable only in their original LTR position on the left side, creating a confusing user experience.

Current behavior: In RTL mode, checkboxes appear on the right but can only be clicked on the left side where they would be in LTR mode.

New behavior: In RTL mode, checkboxes are both visually positioned and clickable on the right side, matching user expectations.

Motivation: This fix ensures consistent and intuitive checkbox interaction across different text directions, particularly important for Arabic, Hebrew, and other RTL languages.

Technical Details

Files Modified:

1. lib/src/editor/widgets/text/text_line.dart - Fixed hitTestChildren() method
2. CHANGELOG.md - Added entry under [Unreleased] section

Root Cause:

In text_line.dart, the paint() method correctly positioned checkboxes for RTL text direction, but the hitTestChildren() method continued to use the original LTR offset for hit testing, causing a mismatch between visual position and clickable area.

Solution:

Modified the hitTestChildren() method to apply the same RTL positioning logic as the paint() method:

// Use the same offset calculation as in paint() method for RTL support
final leadingOffset = textDirection == TextDirection.ltr
    ? childParentData.offset
    : Offset(
        size.width - _leading!.size.width,
        childParentData.offset.dy,
      );

Testing:

• Static analysis passed (flutter analyze)
• Manual testing with RTL text direction confirmed the fix
• No impact on LTR text direction functionality

CHANGELOG Entry Added:

## [Unreleased]

### Fixed

- **RTL checkbox click area issue** fixed where checkboxes in RTL text direction were visually positioned correctly but remained clickable only in their LTR position.
