Change size of hamburger icon

I'm trying to change the size of the hamburger icon for the react bootstrap hamburger menu. I need to use 'vw'. This is what I have so far:

import React, { Component } from 'react';
import { MDBNavbar, MDBNavbarBrand, MDBNavbarNav, MDBNavItem, MDBNavLink,             MDBCollapse, MDBContainer,
MDBHamburgerToggler } from 'mdbreact';
import { BrowserRouter as Router } from 'react-router-dom';

class Navbar extends Component {
state = {
  collapse1: false,
  collapseID: ''
}

toggleCollapse = collapseID => () => {
  this.setState(prevState => ({ collapseID: (prevState.collapseID !== collapseID ? collapseID :         '') }));
}

toggleSingleCollapse = collapseId => {
  this.setState({
    ...this.state,
    [collapseId]: !this.state[collapseId]
  });
}

render() {
  const hamburgerWidth = { width: '1vw' }
  return (
    <Router>
      <MDBContainer>
        <MDBNavbar className="w-100" color="black" style={{ marginTop: '0vw' }} light>
          <MDBContainer >
            <MDBNavbarBrand style={{ color: 'white', fontSize: '4vw'}}>
              Select Page
            </MDBNavbarBrand>
            <MDBHamburgerToggler style={hamburgerWidth} color="#EF542A" id="hamburger1"         onClick={()=> this.toggleSingleCollapse('collapse1')} />
              <MDBCollapse isOpen={this.state.collapse1} navbar>
                <MDBNavbarNav center style={{backgroundColor: 'white'}}>
                  <MDBNavItem active>
                    <MDBNavLink style={{ color: 'white' }} to="#!">Home</MDBNavLink>
                  </MDBNavItem >
                  <MDBNavItem >
                    <MDBNavLink style={{ color: 'white'}} to="#!">Link</MDBNavLink>
                  </MDBNavItem>
                  <MDBNavItem >
                <MDBNavLink to="#!" style={{ color: 'white'}}>Profile</MDBNavLink>
              </MDBNavItem>
            </MDBNavbarNav>
          </MDBCollapse>
      </MDBContainer>
    </MDBNavbar>
  </MDBContainer>
</Router>
);
  }
}

export default Navbar;

This however does not work. Any help would be greatly appreciated.
