legacy_gantt_chart 4.3.2 changelog

4.3.2 #

FIX: Fix for an issue that prevented the options menu on a task from being clicked

4.3.1 #

FIX: Fix bulk actions performance in web browsers
FIX: Fix bulk websocket sync executed sequentially

4.3.0 #

FEATURE: Implement bulk update over websocket

4.2.0 #

FEATURE: Implement web worker for offline database
FEATURE: Implement message queuing for offline database

4.1.1 #

FIX: Fix for an issue that caused a range error when calculating offsets on visible rows during data reset
EXAMPLE FIX: Clear dependencies when resetting data

4.1.0 #

FEATURE: Implemented the ability to select a group of tasks and move them in bulk
FEATURE: Enhanced Axis Labels to be contextual:
- The first visible tick now always displays the Date (e.g., "Oct 10") instead of just time, providing immediate context.
- Ticks crossing into a new day also display the Date.
FEATURE: Implemented Adaptive Axis Ticks logic to prevent label overlap when zooming out.
EXAMPLE FIX: Fixed a visual "drift" issue where the visible date range would jump unexpectedly when resizing the window; the chart now correctly maintains the scroll offset.
FIX: Fixed Axis Tick Alignment to respect local timezones, ensuring ticks land on "round" hours (e.g., 00:00, 12:00) rather than UTC-shifted offsets.
FIX: Fixed Axis Header visibility issue by correcting the painter's Y-coordinate logic.

FIX: Adjust pubignore to remove gif from package

2.10.0 #

FEATURE: Added comprehensive keyboard navigation and accessibility support.
- Added focusedTaskId, onFocusChange, and onRowRequestVisible properties to enable external state management of task focus.
- The chart now internally handles Tab and Shift+Tab key presses to cycle focus between tasks.
- A visual focus indicator (border) is now drawn around the task specified by focusedTaskId.
- The chart now automatically scrolls (pans) vertically and horizontally to bring the focused task into view if it is off-screen.
- Added onRowRequestVisible callback, allowing the parent application to react when a hidden task (e.g., in a collapsed row) is focused.
EXAMPLE FEATURE: The example application was updated to fully demonstrate the new keyboard navigation features.
- Clicking a task now sets it as the focused task, unifying mouse and keyboard selection.
- The focused task state is now managed in the GanttViewModel, preserving focus across rebuilds (e.g., when expanding/collapsing rows).
- Implemented the onRowRequestVisible callback to automatically expand parent rows when a hidden child task is focused via keyboard navigation.

2.9.4 #

FIX: Fix for an issue that caused difficulty grabbing a drag handle to resize the task when task width is small.

2.9.3 #

EXAMPLE FIX: Fix the auto-scaling axis timeline formatting in the example application (day/hour/minute, etc).

2.5.0 #

FEATURE: Added the ability to populate blank rows (rows with no assignments/jobs/events populated)

2.4.0 #

FEATURE: Added noDataWidgetBuilder to LegacyGanttChartWidget to allow developers to provide a custom widget to display when there are no tasks.
FIX: Resolved an issue where the chart would show an infinite loading indicator when the dataset was empty. The chart now correctly displays the "No data to display" message or the custom widget provided via noDataWidgetBuilder.
EXAMPLE: Added 0 to the person and jobs pickers in the example app to demonstrate the "no data" case.
EXAMPLE: Introduced a loading state to the example app's view model to correctly handle the UI difference between "loading" and "empty".

This powerful new feature allows developers to completely replace the default time axis header with a custom Flutter widget, granting full control over the layout, styling, and complexity of the timeline visualization (e.g., multi-level headers for Month/Year/Day).
FEATURE: The height of the timeline axis is now dynamically controlled by the axisHeight property (or the default 27.0 if unset) to correctly size the custom header area.
EXAMPLE FEATURE: The example app was updated to demonstrate the new functionality, allowing users to switch to a "Custom" timeline format that displays a two-level header (Month/Year over Day number) using the new builder.
