如何在InputText字段中设置react native中的数字必须为10位

import { TextInput } from 'react-native';

state = {
  inputValue: ''
}

handleChangeText = (text) => {
  this.setState({ inputValue: text });
}

render() {
  return (
    <TextInput
      onChangeText={this.handleChangeText}
      value={this.state.inputValue}
    />
  );
}

handleChangeText = (text) => {
  if (text.length === 10 && /^\d+$/.test(text)) {
    this.setState({ inputValue: text });
  }
}
