ErikDakoda commented 3 years ago

An adaptation of Vulcan's flash message system, but using reactive state instead of React context
Updated withMessages to use reactive state
Added new useMessages hook
Added new useIntl hook
Separated FlashMessages component into its own file
Updated Flash component to use reactive state
Moved getProperties() from the Flash component to normalizeMessage() in withMessages
Added new Material UI implementation of the Flash component
Removed messages from the state of the App component, MessageContext from the component tree, and the methods UNSAFE_componentWillMount, componentWillUnmount, flash, and clear
Removed messages.js, which only defined MessageContext
Updated error.js to report the http status of network errors thrown by Apollo

NOTE: This PR depends on #2675 and #2676
