switchToFeature method

void switchToFeature(FeatureNavigationConfiguration feature)

Switches to feature, saving the current URI so it can be restored when this feature is switched back to.

Implementation

void switchToFeature(FeatureNavigationConfiguration feature) {
  try {
    final router = _getRouter();
    final navigator = _getMultilevelNavigator();

    );

    // Re-tapping the active feature in multi-column mode at depth >=3:
    // toggle level2 if it's part of the current layout, otherwise open it
    // by navigating to its path (e.g. a window showing only level1+level3).
    final multilevelBloc = _maybeReadMultilevelBloc();
    if (multilevelBloc != null && currentFeature?.key == feature.key) {
      final multilevelState = multilevelBloc.state;
