NativeBase Formik UI

@native-base/formik-ui is the official NativeBase - Formik bindings by NativeBase Team. @native-base/formik-ui provides with form components integrated with formik hooks out of the box, Each component makes use of Formik's context, therefore you need to have Formik installed in your project, after that all you have to do is write your validationSchema, build your Form using NativeBase Formik UI components and wrap that with <Formik/> , rest will be taken care by us.

Here is an example of CheckboxControl provided by NativeBase Formik UI

import React from 'react';
import {
  CheckboxControl,
  Text,
  SubmitButton,
  ResetButton,
  Box,
  ButtonGroup,
} from '@native-base/formik-ui';
import { Formik } from 'formik';
import { Heading, Center, NativeBaseProvider } from 'native-base';
import * as Yup from 'yup';

const validationSchema = Yup.object().shape({
  tnc: Yup.boolean().equals([true], 'Terms and Condition must be checked !'),
  newsletter: Yup.boolean(),
});

function FormikCheckboxBasicExample() {
  const onSubmit = async (values) => {
    await new Promise((resolve) => setTimeout(resolve, 1000));
    console.log(values);
  };
  return (
    <Formik
      initialValues={{
        tnc: true,
        newsletter: false,
      }}
      onSubmit={onSubmit}
      validationSchema={validationSchema}
    >
      {({ values, errors }) => (
        <Box>
          <Heading>Checkbox FormControl</Heading>
          <CheckboxControl name="tnc" label="Checkbox Control Label" mt={4}>

          </ButtonGroup>
          <Box mt={4} bg="gray.100" p={3}>
            <Heading size="sm" mb={2}>
              Current State
            </Heading>
            Values: {JSON.stringify(values, null, 2)}
            Errors: {JSON.stringify(errors, null, 2)}
