it fixes the issue If you are doing this in react, it would probably be beneficial to re-implement this script in a more natural way. For example:
import React from 'react';

export default class Blinker extends React.PureComponent {

    state = {
        message: 'This is side',
        side: 'A'
    };

    componentDidMount() {
        this.timerId = setInterval(() => this.tick(), 500);
    }

    tick = () => {
        let newSide;
        if (this.state.side === 'A') {
            newSide = 'B';
        } else {
            newSide = 'A';
        }
        this.setState({ side: newSide });
    };

    render() {
        return <span>{this.state.message} {this.state.side}</span>;
    }
}

this one helps. is it possible to separate var styles = StyleSheet.create from React.component into different script in react native? , that's possible. just create a js file with this pattern:
'use strict';

var React = require('react-native');

var myStyles = React.StyleSheet.create({
   style1: { },
   style2: { }
)}

module.exports = myStyles;
var s = require('../the/path/to/phongyewtong');
<View style = {s.style1} />

hope this fix your issue You can do something very similar to what you've tried to do, you just need to return valid JSX

How in React JSX to pass a parent custom react component state attribute value to child customer component?

it should still fix some issue You can use React.Children and React.cloneElement api in your MyCustomRectComponentA component.
eg:
import React, { Component, Children , cloneElement } from 'react'

class MyCustomRectComponentA extends Component {
    state = {
        offset: '50px'
    }
    render() {
        return (
            <div>              
                // mapping through every children elements
                // passed to "MyCustomRectComponentA" component
                {Children.map(this.props.children, child => { 
                    // you have to clone the child element
                    // because they are read-only 
                    // and pass the "state" as props
                    return cloneElement(child, {
                     offsetValue: this.state.offset 
                    })
                })}
            </div>
        )
    }   
}

export default MyCustomRectComponentA
 public render() {
    return (
      <MyCustomRectComponentA>
        <AnotherCustomComponentB />
      </MyCustomRectComponentA>
    );

  }
