Not able to access controller

• OS: [iOS]
• Package version [3.5.1]

 constructor(props) {
    super(props);
    this.categoryController;
    this.state = {
    category: null
                  }
}

 <DropDownPicker
                  items={this.state.categoryList}
                  placeholder={"Select category"}
                  defaultValue={this.state.category}
                  controller={(instance) =>
                    (this.categoryController = instance)
                  }
                 .....
                ...../>

When I try to access the controller this.categoryController.reset();

Crash: Error:

I cleared the cache using

npm start -- --reset-cache

and ran the project again, now i’m not getting the exception anymore

Please add your component code fully (not just the picker).
