アプリのフォームにFormikyupを使用しています。Formikでチェックボックスを実装できません。このソリューションを実装しましたが、私とは連携していません。以下は、これまでに試したコードです。チェックボックスをクリックするとこのソリューションを実装した後、フォームが無効になり、送信ボタンがメソッドを呼び出しません。代わりに使ってみましたが、結果は同じでした。handleSubmitReact Native ElementsUI Kitten

const validationSchema = Yup.object().shape({

  service_charge_status: Yup.boolean(),//.oneOf([true], 'Please check the agreement'),

    .required('Security Number is required'),
  note: Yup.string().label('Note')
