Image Load Speed Much more Lower than NetworkImage

[lucasjinreal]

I have some comparation, when a image is big, advanced_networkimage always failed to load image (actually it keep try accesing my image from cloud, but not continuely loading just somewhat corrupt loading and then start it over again failing at last).

But NetworkImage can load image success eventually and much more faster than this lib.

Such as this image

Since the image is big, then it will fail load , this is terrible, and it is slower than NetworkImage

Please provide version info.

  flutter_advanced_networkimage: ^0.5.0

I don't see any problems with your url, can you post the code about comparation?

[lucasjinreal]

@mchome Not url, the image can be shown, but very slow. NetworkImage can show, but AdvancedNetwork sometime fail and can not show image.

if (userAvatarUrl != null && userAvatarUrl != '') {
      // userAvatarImage = AdvancedNetworkImage(userAvatarUrl);
      userAvatarImage = NetworkImage(userAvatarUrl);
    } else {
      userAvatarImage = AssetImage('assets/images/blank_avatar.png');
    }

I am using this widget in a data model:

class Group {
  Group({
    @required this.group_avatar,
    @required this.group_name,
    @required this.group_desc,
    @required this.group_create_time,
    @required this.group_create_timestamp,
    @required this.group_addr,
    this.group_members_num,
    this.groupAvatarImage,
    this.isOwner,
    this.group_avatar_url
  });

  final String group_avatar;
  final String group_avatar_url;
  final String group_name;
  final String group_desc;
  final String group_create_time;
  final String group_create_timestamp;
  final String group_addr;
  int group_members_num;
  bool isOwner;
  ImageProvider groupAvatarImage;

you should set the retryLimit to the biggest number as possible
AdvancedNetworkImage(imgUrl, retryLimit: Duration.secondsPerDay)
also set the retryDurationFactor to zero
and the retryDuration is set to Duration(milliseconds: 500) by default no need to be changed.

Hello? How does preProcessing work in AdvancedNetworkImage?
My data url from map is so lazy before appearing in my return container and i would like to show the image before caching it to avoid Failed cache. Thank in advance.

[lucasjinreal]

extend_image would be better

Thank you @jinfagang!

[mchome]

@SirBlank preProcessing was for someone who want to manipulate the image(e.g. bluring) before caching. I think you'd better using futurebuilder for lazy data.

[ghost]

I think , Instead of using extend_image, it would be better use the fallbackAssetImage and fallbackImage from AdvanceNetworkImage. what I'm trying to achieve is that the data from url will display before catching. anyway thank you again :)

@mchome Thank you sir! :)
