The types of errors and loading.

SectionErrors and loadingDraftDocumented, not reviewed yet: the API can change.

ErrorFallbackProps

Interface

What errorFallback gets: the error, the screen, and retry, which renders the screen again. When the start failed, the screen is the first root it shows in, and retry runs the start again from willMount.

interface ErrorFallbackProps

Member	Type	Description
errorRequired	unknown
screenRequired	ScreenInfo
retryRequired	() => void

Defined in src/api/screens/ScreenBoundary.tsx ↗

LoadingFallback

Type

What a screen shows while it waits for a lazy component or data.

type LoadingFallback = ComponentType<{ screen: ScreenInfo }>

Defined in src/api/screens/registerScreens.tsx ↗

NavigationErrorSource

Type

Where an error that goes to onError came from.

type NavigationErrorSource =
  /** A screen failed to render: it shows `errorFallback`, or nothing, and the other screens go on. */
  | { type: 'screen'; screen: ScreenInfo; componentStack?: string | null }
  /**
   * The app failed to start: `willMount` or the first root. `errorFallback` shows as the first screen, and its `retry`
   * starts again; without it the splash screen stays, and the next launch tries again.
   */
  | { type: 'start' }
  /** A route of `linking` failed: its `start`, its `open`, or a command they made. The app goes on. */
  | { type: 'link'; url: string }

Member	Type	Description
typeRequired	'screen'
screenRequired	ScreenInfo
componentStack	string | null
urlRequired	string
