A convenient way to use material-ui's snackbars.

npm i --save material-ui-snackbar-provider

Simply wrap all components that should display snackbars with the SnackbarProvider component, e.g. by wrapping your router with it.

import { SnackbarProvider } from 'material-ui-snackbar-provider'

// somewhere at the root of your app
<SnackbarProvider SnackbarProps={{ autoHideDuration: 4000 }}>
  {/* the rest of your app belongs here, e.g. the router */}
</SnackbarProvider>

You can then display messages with the useSnackbar hook.

import { useSnackbar } from 'material-ui-snackbar-provider'

export default function MyComponent (props) {
  const snackbar = useSnackbar()

  const handleSomething = () => {
    snackbar.showMessage(
      'Something happened!',
      'Undo', () => handleUndo()
    )
  }

  const handleUndo = () => {
    // *snip*
  }

  return (
    // *snip*
  )
}

If you're not using React ^16.8.0 and our you can't use hooks (e.g. in a class component), you can use the withSnackbar HOC and the injected snackbar prop instead.

import { withSnackbar } from 'material-ui-snackbar-provider'

class MyComponent {
  // *snip*

  handleSomething () {
    this.props.snackbar.showMessage(
      'Something happened!',
      'Undo', () => this.handleUndo())
  }

  handleUndo () {
    // *snip*
  }
}

export default withSnackbar()(MyComponent) // export the wrapped component

* required property

snackbar.showMessage(message, [action, handler])

• message (string) – message to display
• action (string, optional) – label for the action button
• handler (function, optional) – click handler for the action button

Dude, this is not pretty React-like, I don't want to call a function to do something that changes the UI! I want to display a snackbar based on the state only, e.g. by using Redux.

I agree. And if it wouldn't be an absolute pain to do that if you intend to display more than one snackbar, this package wouldn't even exist. The thing is that most of the time, snackbars are displayed when state changes and not really depend on the state itself.

Also, calling a method after dispatching the action is pretty convenient, especially when using something like redux-thunk:

deleteEmail (id) {
  this.props.dispatch(someReduxThunkAction())
  .then(() => {
    this.snackbar.showMessage(
      'E-mail deleted',
      'Undo', () => this.restoreEmail(id))
  })
  .catch((e) => {
    this.snackbar.showMessage(
      'E-mail could not be deleted',
      'Retry', () => this.deleteEmail(id))
  })
}

So this package makes snackbars a lot easier to use, which is all it's intended to do.
