canPop method

bool canPop (
  1. BuildContext context
)

Whether the navigator that most tightly encloses the given context can be popped.

The initial route cannot be popped off the navigator, which implies that this function returns true only if popping the navigator would not remove the initial route.

If there is no Navigator in scope, returns false. See also:

Implementation

static bool canPop(BuildContext context) {
  final NavigatorState navigator = Navigator.of(context, nullOk: true);
  return navigator != null && navigator.canPop();
}
