}) {
  return MyState(
    error: error is VooUnsetValue ? this.error : error as String?,
  );
}

0.7.18 #

  • Added UTC Offset DateTime Format for OData Filters
    • Added ODataDateTimeFormat.utcOffset enum value for explicit timezone offset formatting
    • Formats DateTime values as 2024-09-30T15:15:30.000+00:00 instead of 2024-09-30T15:15:30.000Z
    • Solves compatibility issues with .NET OData DateTimeOffset + PostgreSQL timestamptz configurations

0.7.15 #

  • Configurable DateTime Format for OData Filters

      • Best for PostgreSQL timestamp with time zone columns
      • Works with most OData implementations that properly handle UTC
    • ODataDateTimeFormat.unspecified: ISO 8601 without 'Z' suffix (e.g., 2024-09-30T15:15:30.000)
      • Use for .NET backends where OData creates DateTime.Kind=Unspecified
      • Compatible with SQL Server datetime and other non-timezone-aware columns
      • Prevents "DateTime with Kind=Unspecified" errors when backend doesn't handle UTC strings properly
    • DateTime values are still converted to UTC internally, only the 'Z' suffix is affected

0.5.3 #

  • Bug Fixes

    • Fixed Generic Type Parameter Propagation in Filter Row

      • Fixed type mismatch error that occurred when clicking on filters with typed controllers
      • Added missing generic type parameters to all filter-related methods in VooDataGridFilterRow
      • Methods updated: _buildFilterInput, _buildTextFilter, _buildNumberFilter, _buildNumberRangeFilter, _buildDateFilter, _buildDateRangeFilter, _buildDropdownFilter, _buildMultiSelectFilter, _buildCheckboxFilter, _getFilterOptions, and _applyFilter
      • This ensures proper type safety when using typed controllers like VooDataGridController<OrderList>
      • Users no longer need to explicitly add type parameters to columns when using typed controllers

    • Improved VooApiStandard Number Range Filtering

      • Enhanced handling of between operator to properly handle null min/max values
      • Now only creates GreaterThanOrEqual filter when minimum value is not null
      • Only creates LessThanOrEqual filter when maximum value is not null
      • Allows filtering with just a minimum or just a maximum value

    • VooApiStandard Field Name PascalCase

      • Fixed field names to use PascalCase after the prefix in VooApiStandard
      • When using fieldPrefix='Site' with field='siteNumber', it now correctly generates 'Site.SiteNumber' (not 'Site.siteNumber')
      • This ensures compatibility with backend APIs expecting PascalCase field names
      • Other API standards continue to use the field name as-is without case changes

0.5.2 #

      • Added try-catch blocks around valueGetter calls to prevent crashes
      • Improved error logging with detailed type information for debugging
      • Better error messages when valueGetter is missing for typed objects
      • Graceful fallback to null values on errors instead of crashing

    • VooApiStandard Number Range Fix: Fixed number range filtering for Voo API Standard

      • Number ranges now correctly use GreaterThanOrEqual and LessThanOrEqual operators
      • Removed unsupported 'Between' operator from Voo API Standard
      • Creates two separate filters for range queries as expected by the API
      • Example: Site.siteNumber between 0 and 100 now sends:
        • {fieldName: 'Site.siteNumber', value: 0, operator: 'GreaterThanOrEqual'}
        • {fieldName: 'Site.siteNumber', value: 100, operator: 'LessThanOrEqual'}

    • Filter Visibility During Errors: Fixed filters disappearing when data loading fails

      • Headers and filter row now remain visible even when there's an error
      • Users can adjust filters and retry without losing their filter state
      • Error message appears in the data area while preserving the grid structure
      • Improves user experience by maintaining context during error states

  • Developer Experience

    • Added detailed debug logging for type mismatches
    • Created comprehensive error handling tests
    • Better documentation of type safety requirements
    • Clearer error messages to help developers debug issues

    • Updated filter row to skip columns with excludeFromApi flag
    • Updated header to prevent sorting on excluded columns
    • Added InkWell wrapper for cells with onCellTap callback

  • Use Cases

    • Action buttons (edit, delete, view) that shouldn't be sent to API
    • Clickable cells for quick actions
    • Local-only columns that don't exist in the backend

  • Examples

    • nested_field_example.dart: Demonstrates field prefix usage
    • action_buttons_example.dart: Shows action columns with edit/delete/view buttons

  • Testing

    • Added tests for field prefix functionality
    • Added tests for excludeFromApi and onCellTap features

    • Better IDE support with autocomplete and error detection
    • Cleaner, more maintainable code with compile-time type checking
    • Backward compatible - can still use dynamic for untyped/Map data
