PickerDataAdapter<T> class

A picker adapter for array-based and hierarchical data structures.

PickerDataAdapter is the most commonly used adapter that supports both simple arrays and complex hierarchical data. It can handle:

• Simple lists: ['Option 1', 'Option 2', 'Option 3']
• Multi-dimensional arrays for independent columns
• Hierarchical maps for linked columns: {'Category': ['Item1', 'Item2']}
• Mixed data types with custom PickerItem objects

Simple Array Example

final adapter = PickerDataAdapter<String>(
  pickerData: ['Apple', 'Banana', 'Orange'],
);

Multi-Column Array Example (Independent Columns)

final adapter = PickerDataAdapter<String>(
  pickerData: [
    ['Red', 'Green', 'Blue'],     // Column 1: Colors
    ['Small', 'Medium', 'Large'], // Column 2: Sizes
  ],
  isArray: true,
);

Hierarchical Example (Linked Columns)

final adapter = PickerDataAdapter<String>(
  pickerData: [
    {
      'Fruits': ['Apple', 'Banana', 'Orange'],
      'Vegetables': ['Carrot', 'Broccoli', 'Spinach'],
    }
  ],
);

Custom PickerItem Example

final adapter = PickerDataAdapter<String>(
  data: [
    PickerItem<String>(
      text: Row(children: [Icon(Icons.apple), Text('Apple')]),
      value: 'apple',
    ),
    PickerItem<String>(
      text: Row(children: [Icon(Icons.android), Text('Banana')]),
      value: 'banana',
    ),
  ],
);
