If you are using hooks you can add an useEffect with the code:
useEffect(() => {
form.setFieldsValue(defaultValues)
}, [form, defaultValues])
Remember define the form value first:
const [form] = Form.useForm()
And remember to pass this form instance to the Form component:
<Form
form={form}
layout="vertical"
name="form-name"
initialValues={defaultValues}
onFinish={submitHandler}
>
In this form, you going to update the defaultValues when the component renders.
If you are using classes, you can put the code inside componentDidUpdate lifecycle method.
