TemplateRef type checking/declaring type

Lets assume I have component with generic type that displays data list:

interface DataProvider<T> {
  getData(): T[];
}

...
template: '<div *vsFor="let item in dataProvider.getData()">
    <ng-container *ngTemplateOutlet="rowTemplate; context:{item: item}">
    </ng-container>
</div>'
...
class AwesomeList<T> {
  @Input dataProvider: DataProvider<T>;
  @Input rowTemplate: TemplateRef<T>;
}

Some problem appears, when I use it:

<awesome-list [dataProvider]="provider" [rowTemplate]="template"></awesome-list>

<ng-template #template let-object="item">
{{object.name}} // Here, type of object is unclear (?)
</ng-template>

So is any way to defined object/item class here?

P.S. All this work ok, but I want to end with strict types, autocomplete in IDE, etc.
