public static final @NonNull SavedStateHandle SavedStateHandleFactoryKt.invoke(
    @NonNull SavedStateHandle.Companion receiver,
    @NonNull Object route,
    @NonNull Map<@NonNull KType, @NonNull NavType<@NonNull ?>> typeMap
)

SavedStateHandle constructor to create a SavedStateHandle with a serializable object.

Returns a SavedStateHandle populated with arguments from route.

Note: To use this api in non-instrumented tests, run with robolectric. This is because android's Bundle is necessarily integrated into the parsing of route arguments.

Parameters
`@NonNull Object route`	The route to extract argument values from
`@NonNull Map<@NonNull KType, @NonNull NavType<@NonNull ?>> typeMap`	A mapping of KType to custom NavType<*> in the `route`. May be empty if `route` does not use custom NavTypes.
