It is easy to understand how to use form. Reading following source is better way to do that.

Form

<View style={form.base.container}>
  <Form
    onSubmit={({ result, errors, messages }) => {
      if (result) {
        Alert.alert('Login Success!!')
      } else {
        Alert.alert(messages[0])
      }
      this.setState({ submit: false })
    }}
    trigger={this.state.submit}
  >
    <TextField
      label="Email"
      name="email"
      value={this.state.email}
      onChangeText={email => this.setState({ email })}
      placeholder="input your email..."
      required
      email={{
        message: 'Please Write Your Custom Error Message for Email'
      }}
    />
    <TextField
      label="password"
      name="password"
      value={this.state.password}
      onChangeText={password => this.setState({ password })}
      secureTextEntry={true}
      placeholder="******"
      message="Password must be 6-8 characters in length "
      required
      format={{
        message: 'Please Write Your Custom Error Message for Format',
        regexp: '[A-Za-z0-9]{6,8}'
      }}
    />
    <ButtonSuccess
      title="Login"
      onPress={() => this.setState({ submit: true })}
    />
  </Form>
</View>

If you pass pros "name" and "value" to component to want to validate. And, set the trigger to start to validate. Form watch trigger and when trigger is true, form start to validate.

When form finish to validate, it returns error object like following source in onSubmit.

onSubmit={({ result, errors, messages }) => {
  if (result) {
    Alert.alert('Login Success!!')
  } else {
    Alert.alert(messages[0])
  }
  this.setState({ submit: false })
}}

If you want to validate or do something depend on result of that before submit, you can implement the process as you like.

Field

You can use field like other react native components.

import { CreditCardNumber } from 'react-native-various-form'

<View style={fields.container}>
  <Text style={fields.label}>Let's Try</Text>
  <CreditCardNumber
    style={fields.component}
    value={this.state.value}
    onChangeText={text => this.setState({ value: text })}
  />
</View>
