Violation invariante non capturée: Trop de renoncres. React limite le nombre de rendus pour empêcher une boucle infinie

Question

J'essaie d'ajouter un snackbar afin d'afficher un message chaque fois qu'un utilisateur signé ou non. Snackbar.jsx:

import React from "react";
import PropTypes from "prop-types";
import classNames from "classnames";
import CheckCircleIcon from "@material-ui/icons/CheckCircle";
import ErrorIcon from "@material-ui/icons/Error";
import CloseIcon from "@material-ui/icons/Close";
import green from "@material-ui/core/colors/green";
import IconButton from "@material-ui/core/IconButton";
import Snackbar from "@material-ui/core/Snackbar";
import SnackbarContent from "@material-ui/core/SnackbarContent";
import { withStyles } from "@material-ui/core/styles";

const variantIcon = {
  success: CheckCircleIcon,
  error: ErrorIcon
};

const styles1 = theme => ({
  success: {
    backgroundColor: green[600]
  },
  error: {
    backgroundColor: theme.palette.error.dark
  },
  icon: {
    fontSize: 20
  },
  iconVariant: {
    opacity: 0.9,
    marginRight: theme.spacing.unit
  },
  message: {
    display: "flex",
    alignItems: "center"
  }
});

function SnackbarContentWrapper(props) {
  const { classes, className, message, onClose, variant, ...other } = props;
  const Icon = variantIcon[variant];

  return (
    <SnackbarContent
      className={classNames(classes[variant], className)}
      aria-describedby="client-snackbar"
      message={(
        <span className={classes.message}>
          <Icon className={classNames(classes.icon, classes.iconVariant)} />
          {message}
        </span>
      )}
      action={[
        <IconButton
          key="close"
          aria-label="Close"
          color="inherit"
          className={classes.close}
          onClick={onClose}
        >
          <CloseIcon className={classes.icon} />
        </IconButton>
      ]}
      {...other}
    />
  );
}

SnackbarContentWrapper.propTypes = {
  classes: PropTypes.shape({
    success: PropTypes.string,
    error: PropTypes.string,
    icon: PropTypes.string,
    iconVariant: PropTypes.string,
    message: PropTypes.string,
  }).isRequired,
  className: PropTypes.string.isRequired,
  message: PropTypes.node.isRequired,
  onClose: PropTypes.func.isRequired,
  variant: PropTypes.oneOf(["success", "error"]).isRequired
};

const MySnackbarContentWrapper = withStyles(styles1)(SnackbarContentWrapper);

const CustomizedSnackbar = ({
  open,
  handleClose,
  variant,
  message
}) => {
  return (
    <div>
      <Snackbar
        anchorOrigin={{
          vertical: "bottom",
          horizontal: "left"
        }}
        open={open}
        autoHideDuration={6000}
        onClose={handleClose}
      >
        <MySnackbarContentWrapper
          onClose={handleClose}
          variant={variant}
          message={message}
        />
      </Snackbar>
    </div>
  );
};

CustomizedSnackbar.propTypes = {
  open: PropTypes.bool.isRequired,
  handleClose: PropTypes.func.isRequired,
  variant: PropTypes.string.isRequired,
  message: PropTypes.string.isRequired
};

export default CustomizedSnackbar;

SigninformContainer.jsx:

import React, { useState } from 'react';
import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import SnackBar from '../../components/SnackBar';
import SignInForm from './SignInForm';

const SingInContainer = ({ message, variant}) => {
    const [open, setSnackBarState] = useState(false);
    const handleClose = (reason) => {
        if (reason === 'clickaway') {
          return;
        }
        setSnackBarState(false)

      };

    if (variant) {
        setSnackBarState(true);
    }
    return (
        <div>
        <SnackBar
            open={open}
            handleClose={handleClose}
            variant={variant}
            message={message}
            />
        <SignInForm/>
        </div>
    )
}

SingInContainer.propTypes = {
    variant: PropTypes.string.isRequired,
    message: PropTypes.string.isRequired
}

const mapStateToProps = (state) => {
    const {variant, message } = state.snackBar;

    return {
        variant,
        message
    }
}

export default connect(mapStateToProps)(SingInContainer);

Quand j'exécute l'application, j'ai reçu cette erreur:

Invariant Violation: Too many re-renders. React limits the number of renders to prevent an infinite loop.

Le problème est dû au composant SnackBar. J'utilise le useStatehooks afin de changer l'état de la barre de snackbar. Devrais-je utiliser une classe et un componentShouldUpdate afin de ne pas rendu plusieurs fois?

Vous pouvez empêcher cette erreur en utilisant des crochets dans une fonction
