Flutter Future<List<Image>> convert to List<Image>

List<Image> convertToImgList(Future<List<Image>> listimg) {
  var li = listimg.asStream();
  Future<int> future = listimg.asStream().length;
  return images;
}

Hi,
I want to convert Future List Image to List Image in flutter.
Anyone knows how it can be done?

    It is future so you much wait for it by await:

    void main () async {
  Future<List<Image>> listimg = _yourFutureData();
  List<Image> imageList = await listimg;
}

    Convert from Future<List<Image>>

    final Future<List<Image>> listFutureImages = Future<List<Image>>();
final List<Image> listImages = await listFutureImages;

    Convert from List<Future<Image>>

    final Future<List<Image>> listFutureImages = List<Future<Image>>();
final List<Image> listImages = await  Future.wait(
   listFutureImages.map(
      (e) async => await e,
   ),
);
