saka_image #

A flutter image widget,can use placeholder before loading net_image, also can show an error image if there is something wrong with the image url

Getting Started #

just like use Image.network

SakaImage.urlWithPlaceHolder(
  "http://img.rangaofei.cn/01b18.jpg",
  prePlaceHolder: "images/test.gif",
  errPlaceHolder: "images/error.jpeg",
  preDuration: Duration(seconds: 10),
);

prePlaceHolder is used before load the net image

errPlaceHolder is user when the url not correct

preDuration is the prePlaceHolder show duration at least

other property is just like Image

  1. with no duration,when the net image get completed, the pre placeholder will be placed immediately.
SakaImage.urlWithPlaceHolder(
  "http://img.rangaofei.cn/01b18.jpg",
  errPlaceHolder: "images/error.jpeg",
  prePlaceHolder: "images/splash.jpg",
  fit: BoxFit.cover,
);
  1. with duration,when the net image get completed before the duration, the placeholder will not be placed until the duration.
SakaImage.urlWithPlaceHolder(
  "http://img.rangaofei.cn/01b18.jpg",
  errPlaceHolder: "images/error.jpeg",
  prePlaceHolder: "images/splash.jpg",
  preDuration: Duration(seconds: 5),
  fit: BoxFit.cover,
);
  1. if the url is not reachable or error, this will be replaced by the error.jpeg
SakaImage.urlWithPlaceHolder(
  "http://img.rangaofei.cn/01b18.jp",//errorr
  errPlaceHolder: "images/error.jpeg",
  prePlaceHolder: "images/splash.jpg",
  preDuration: Duration(seconds: 5),
  fit: BoxFit.cover,
);

the placeholder must be an assets url

The package description is too short. (-20 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Package is getting outdated. (-11.23 points)

The package was last published 58 weeks ago.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
