Sample for adding external image editors.
(You can replace ImageEdit widget by your owned image editor widget, that output file after editing finised)

configs.externalImageEditors['external_image_editor_1'] = EditorParams(
      title: 'external_image_editor_1',
      icon: Icons.edit_rounded,
      onEditorEvent: (
              {required BuildContext context,
              required File file,
              required String title,
              int maxWidth = 1080,
              int maxHeight = 1920,
              int compressQuality = 90,
              ImagePickerConfigs? configs}) async => await Navigator.of(context).push(MaterialPageRoute<File>(
              fullscreenDialog: true,
              builder: (context) => ImageEdit(file: file, title: title, maxWidth: maxWidth, maxHeight: maxHeight, configs: configs)))
  );

Sample for usage

// Get max 5 images
List<ImageObject> objects =
    await Navigator.of(context).push(
        PageRouteBuilder(pageBuilder:
            (context, animation, __) {
  return ImagePicker(maxCount: 5);
}));

if (objects.length > 0) {
  setState(() {
    imageFiles.addAll(objects
        .map((e) => e.modifiedPath)
        .toList());
  });
}
