Submission

To submit form you need to invoke submit(params) method. This method is not customizable itself, but it invokes customizable prop onStartSubmit and then onEndSubmit.

Default behavior

onStartSubmit

Params: form, params (params, that were passed to submit method)

Returns: promise, that should be resolved on end submission

First of all, there are some preparations:

• Set submitting form meta to true.
• Set touched for all fields
• Increment submitCount + 1

Next, it runs general form validation. If form is valid after validation, it calls onSubmit method.

onSubmit

Params: form, params

Returns: promise, that should be resolved on end submission

By default, the behavior of this method is not defined. It's designated to run your submit request.

onEndSubmit

Params: form, params

This method calls every time when submit is completed. By default, it just sets submitting to false.
