Failed form propType: You provided a `value` prop to a form field without an `onChange` handler

When I load my react app I get this error in the console.

Warning: Failed form propType: You provided a value prop to a form field without an onChange handler. This will render a read-only field. If the field should be mutable use defaultValue. Otherwise, set either onChange or readOnly. Check the render method of AppFrame.

My AppFrame component is below:

class AppFrame extends Component {
    render() {
        return (
            <div>
                <header className="navbar navbar-fixed-top navbar-shadow">
                    <div className="navbar-branding">
                        <a className="navbar-brand" href="dashboard">
                            <b>Shire</b>Soldiers
                        </a>
                    </div>
                    <form className="navbar-form navbar-left navbar-search alt" role="search">
                        <div className="form-group">
                            <input type="text" className="form-control" placeholder="Search..."
                                   value="Search..."/>
                        </div>
                    </form>
                    <ul className="nav navbar-nav navbar-right">
                        <li className="dropdown menu-merge">
                            <span className="caret caret-tp hidden-xs"></span>
                        </li>
                    </ul>
                </header>

                <aside id="sidebar_left" className="nano nano-light affix">

                    <div className="sidebar-left-content nano-content">

                        <ul className="nav sidebar-menu">
                            <li className="sidebar-label pt20">Menu</li>
                            <li className="sidebar-label">
                                <IndexLink to="/" activeClassName="active">Dashboard</IndexLink>
                            </li>
                            <li className="sidebar-label">
                                <Link to="/fixtures" activeClassName="active">Fixtures</Link>
                            </li>
                            <li className="sidebar-label">
                                <Link to="/players" activeClassName="active">Players</Link>
                            </li>
                        </ul>

                    </div>

                </aside>
                <section id="content_wrapper">
                    <section id="content" className="table-layout animated fadeIn">
                        {this.props.children}
                    </section>
                </section>
            </div>

        )
    }
}

export default AppFrame;

I am struggling to work out what I am actually doing wrong here. The application starts up and works but I am trying to remove all console warning/errors.

Answer

Try this,

const [email, SetEmail] = useState("");

<Form.Control
    onChange={e => SetEmail(e.target.value)}
    type="email"
    name="email"
    value={email || ""}
/>
