Developer-defined information to be passed along to the navigate event, made available in NavigateEvent.info. This can be any data type. You might, for example, wish to display newly-navigated content with a different animation depending on how it was navigated to (swipe left, swipe right, or go home). A string indicating which animation to use could be passed in as info.
A Promise which will fulfill when all promises returned by the intercept() handler are fulfilled. This is equivalent to the NavigationTransition.finished promise fulfilling, when the navigatesuccess event fires.
Either one of these promises rejects if the navigation has failed for some reason.
Thrown if the Navigation.currentEntry's NavigationHistoryEntry.index value is -1 or 0, i.e., either the current Document is not yet active, or the current history entry is the first one in the history, meaning that backwards navigation is not possible, or if the current Document is unloading.
async function backHandler() {
if (navigation.canGoBack) {
await navigation.back().finished;
// Handle any required clean-up after
// navigation has finished
} else {
displayBanner("You are on the first page");
}
}
async function forwardHandler() {
if (navigation.canGoForward) {
await navigation.forward().finished;
// Handle any required clean-up after
// navigation has finished
} else {
displayBanner("You are on the last page");
}
}
