state bind value, Click to set

state = {
    value: '',
};

// 
handleClick = () => {
    this.setState({ value: null });
}


// render:
<RangePicker value={this.state.value}/>

add the value attribute to the RangePicker to become a controlled component. When emptying, set the value to null

use getFieldDecorator to wrap the RangPicker.
then use setFieldsValue to set its value to undefined

state = {

keyValue: '',

};

give him a key = {this.state.keyValue}
Click to reset this.setState ({keyValue:new Date ()}) and you can empty it, which is equivalent to rendering a new one to achieve

how to do this

how is it emptied
