- **iconPickerShape** (`ShapeBorder`) - Optional - Default: `RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0))` - The shape of the dialog for the picker.
- **backgroundColor** (`Color`) - Optional - Default: `Theme.of(context).dialogBackgroundColor` - The background color for the `AlertDialog`.
- **constraints** (`BoxConstraints`) - Optional - Default: If `adaptiveDialog` is `true`, `BoxConstraints(maxHeight: 500, minWidth: 450, maxWidth: 720)`. Otherwise, `BoxConstraints(maxHeight: 350, minWidth: 450, maxWidth: 678)`. - The dialog's `BoxConstraints` for limiting/setting `maxHeight`, `maxWidth`, `minHeight`, and `minWidth`.
- **title** (`Widget`) - Optional - Default: `Text('Pick an icon')` - The title for the Picker, displayed above the SearchBar and Icons.
- **closeChild** (`Widget`) - Optional - Default: `Text('Close',textScaleFactor: 1.25,)` - The content for the `AlertDialog`'s action `FlatButton` which closes the default dialog.
- **searchIcon** (`Icon`) - Optional - Default: `Icon(Icons.search)` - Sets the prefix icon in the SearchBar.
- **searchHintText** (`String`) - Optional - Default: `'Search'` - Sets the `hintText` in the `TextField` of the SearchBar.
- **searchClearIcon** (`Icon`) - Optional - Default: `Icon(Icons.close)` - Sets the suffix icon in the SearchBar.
- **searchComparator** (`SearchComparator`) - Optional - Default: `(String searchValue, IconPickerIcon icon) => icon.name.toLowerCase().contains(searchValue.toLowerCase())` - A custom search function that should return a `bool`.
- **noResultsText** (`String`) - Optional - Default: `'No results for:'` - Text shown when no search results are found.

- **iconPackModes** (`List<IconPack>`) - Optional - Default: `const <IconPack>[IconPack.material]` - The modes for Icons to show.
- **customIconPack** (`Map<String, IconPickerIcon>`) - Optional - Default: `null` - Customized icons to be used instead of default packs.
- **preSelected** (`IconPickerIcon?`) - Optional - Default: `null` - Pre-selected icon before opening the picker. If non-null, the picker highlights and scrolls to the selected icon.
- **shouldScrollToSelectedIcon** (`bool`) - Optional - Default: `true` - Whether the picker should scroll to the selected icon.
- **selectedIconBackgroundColor** (`Color?`) - Optional - Default: `Theme.of(context).brightness == Brightness.dark ? Colors.grey[800] : Colors.grey[400]` - The background color for the `preSelected` icon.
