Changing Suffix Icon and onTap Action Based on Selected Items State

[dkdanish98]

Description: I am working on a custom MultiDropdown widget in Flutter. I want to dynamically change the suffix icon and its onTap action when _dropdownController.selectedItems is not empty. Currently, this is the following code:

if (_dropdownController.selectedItems.isNotEmpty) {
  return GestureDetector(
    child: const Icon(Icons.clear),
    onTap: () {
      _dropdownController.clearAll();
      _formFieldKey.currentState?.didChange(_dropdownController.selectedItems);
    },
  );
}

Problem: I want to modify the suffix icon (Icons.clear) and its onTap action based on the state of _dropdownController.selectedItems.isNotEmpty. However, I am not sure how to properly implement this feature in my MultiDropdown widget.

Package-Version: multi_dropdown: ^3.0.0-dev.5

In v3.0.0, suffixIcon now accepts a Widget. Please use it to customize.
