How to use the redux/actions.loader function in redux

handleSubmit = async () => {
    const { accountName, privateKey } = this.state

    actions.loader.show(true)

    try {
      await actions.eos.register(accountName, privateKey)
      await actions.eos.getBalance()

      actions.modals.close(constants.modals.EosRegister)
    } catch (e) {
      console.error(e)
      this.setState({ error: e.toString() })
    }

    actions.loader.hide()
  }
