Snackbar

Show transient feedback without interrupting the main task.

This guide covers Material UI Core with the default Emotion engine; extensions and additional demos are explicitly classified.

Use case and business boundary

A timer requests dismissal; the host must update open. Notifications do not implement queues, undo or backend success.

Native composition and scope

Snackbar, SnackbarContent

Preserve native Material UI composition and types; do not substitute JGuang UI/Base UI/Radix APIs. Example entries are not extra components.

Native installation and initialization

npm install @mui/material@9.4.0 @emotion/react@11.14.0 @emotion/styled@11.14.1

Use native npm and Emotion, not an invented JGuang UI Registry URL. Place examples inside native ThemeProvider; choose CssBaseline or ScopedCssBaseline for the project. Inspect React, existing providers, lockfile and SSR first. Never overwrite files or conceal peer conflicts. This batch verified React 19.2.8; React 18 and below require matching react-is. See the included bilingual setup guide.

Practical native parameters

These selected parameters are not a flattened universal API. Preserve the native declaring owner, slot structure, nullable values and generics.

Runnable native examples

Machine keys select example entries, not universal variant props. Native demo JSX/data stay unchanged; JGuang-authored acceptance fixtures are explicitly labelled.

Actual usage example

Unmodified pinned native demo; copy its required local helper files together.

import * as React from 'react';
import Button from '@mui/material/Button';
import Snackbar, { SnackbarCloseReason } from '@mui/material/Snackbar';
import IconButton from '@mui/material/IconButton';
import CloseIcon from '@mui/icons-material/Close';

export default function SimpleSnackbar() {
  const [open, setOpen] = React.useState(false);

  const handleClick = () => {
    setOpen(true);
  };

  const handleClose = (
    event: React.SyntheticEvent | Event,
    reason?: SnackbarCloseReason,
  ) => {
    if (reason === 'clickaway') {
      return;
    }

    setOpen(false);
  };

  const action = (
    <React.Fragment>
      <Button color="secondary" size="small" onClick={handleClose}>
        UNDO
      </Button>
      <IconButton
        size="small"
        aria-label="close"
        color="inherit"
        onClick={handleClose}
      >
        <CloseIcon fontSize="small" />
      </IconButton>
    </React.Fragment>
  );

  return (
    <div>
      <Button onClick={handleClick}>Open Snackbar</Button>
      <Snackbar
        open={open}
        autoHideDuration={6000}
        onClose={handleClose}
        message="Note archived"
        action={action}
      />
    </div>
  );
}

Example dependency boundaries

react, @mui/material/Button, @mui/material/Snackbar, @mui/material/IconButton, @mui/icons-material/Close, @mui/material/Grid, @mui/material/Box, @mui/material/Stack, @mui/material/SnackbarContent, @mui/material/Fade, @mui/material/Slide, @mui/material/Grow, @mui/material/transitions, @mui/material/Alert, @mui/material/AppBar, @mui/material/CssBaseline, @mui/material/GlobalStyles, @mui/material/Toolbar, @mui/icons-material/Menu, @mui/material/Typography, @mui/material/Fab, @mui/icons-material/Add

Direct Icons/System/Utils example imports require their matching 9.4.0 packages. Relative data/helpers are part of the example closure, not extra components. Remote images and simulated operations do not supply a backend.

Pinned upstream API metadata reference

These tables retain the upstream metadata, not a newly inferred generic type system. Conditional generics, inherited props and callback details are defined by the source declarations below. Theme defaults may override metadata defaults.

Snackbar

import Snackbar from '@mui/material/Snackbar';
import { Snackbar } from '@mui/material';

SnackbarContent

import SnackbarContent from '@mui/material/SnackbarContent';
import { SnackbarContent } from '@mui/material';

Native inheritance: Paper. Parent/DOM props are not fabricated as additional own props.

Native source declarations

Declarations/imports are extracted from pinned source without flattening unions or external inheritance. Original English comments/types are source reference, not a claim of translated upstream prose. Shared types stay in their native packages.

Post-install acceptance

Run strict types, production build and real interactions. Check keyboard labels/focus, disabled/error/read-only semantics where natively supported, both themes, narrow screens and reduced motion. Verify callbacks against the real host data; do not declare installation complete from copying a prompt. Initialization fixtures also require server HTML and warning-free hydration.
