dependOn<T extends MomentumController> method
Dependency injection method for getting other controllers. Useful for accessing other controllers' function and model properties without dragging the widget context around.
Implementation
@Deprecated('Use "controller<T>()" instead')
T dependOn<T extends MomentumController>() {
var type = _getType<T>();
if (runtimeType == type) {
throw MomentumError(_formatMomentumLog('[$this]: called '
'"dependOn<$T>()" on itself, you\'re not '
'allowed to do that.'));
}
T? result;
if (_mRootContext != null) {
result = Momentum._ofInternal<T>(_mRootContext!);
} else if (_tester != null) {
result = _tester!.controller<T>();
}
if (result == null) {
throw MomentumError(_formatMomentumLog('[$this]: called '
'"dependOn<$T>()", but no controller of type '
'[$T] had been found.\nTry checking your "Momentum" '
'root widget implementation if the controller '
'"$T" was instantiated there.'));
}
return result;
