Conditionally required schema field

Is it possible? Smth like this:

const schema = yup.object({
  username: yup.string().conditionallyRequired(someVar === anotherVar)
})

@nilamsavani91 You want something like this:

const schema = Yup.object().shape({
  dateField: Yup.date()
    .required('Date is required')
    .typeError('Invalid date'),
  timeField: Yup.string()
    .when('dateField', {
      is: (dateField) => dateField.length > 0,
      then: Yup.string()
        .required('Time field is required')
        .typeError('Time field is required')
    })
});

Thank you. I’ve already achieved it with the following code:

const schema = yup.object({
  password: yup
    .string()
    .when('$user', (user, passSchema) => user
      ? passSchema
      : passSchema.min(6, 'minimal password length is 6 characters').required()),
});
...
<Form
  context={{ user }}
