getParam<T extends RouterParam> method
T?
getParam<T extends RouterParam>()
Get the current route parameters specified using
the params
parameter in MomentumRouter.goto(...)
method.
Example:
// setting the route params.
MomentumRouter.goto(context, DashboardPage, params: DashboardParams(...));
// accessing the route params inside widgets.
var params = MomentumRouter.getParam<DashboardParams>(context);
// accessing the route params inside controllers.
var params = getParam<DashboardParams>();
Implementation
T? getParam<T extends RouterParam>() {
if (_mRootContext == null && _tester != null) {
var router = _tester!._getRouterIfPresent();
if (router != null) {
var param = router.getCurrentParam<T>();
if (param != null && param.runtimeType == _getType<T>()) {
return param;
}
print(
'getParam<$T>() ---> Invalid type: The active/current route param is of type "${param.runtimeType}" while the parameter you want to access is of type "$T". Momentum will return a null instead.');
}
return null;
}
var result = MomentumRouter.getParam<T>(_mRootContext!);
return result;
