canPop method
Whether the navigator 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:
- Route.isFirst, which returns true for routes for which canPop returns false.
Implementation
bool canPop() {
assert(_history.isNotEmpty);
return _history.length > 1 || _history[0].willHandlePopInternally;
}
