Allow network input #5

Closed kobutri closed 2 years ago

One of the most useful use cases for determining the image size without having to parse the entire image is when you load a big image over the network of unknown dimensions and want to determine the layout as early as possible.

The StreamedResponse of Dart's http library already provides a mechanism for accessing part of the data without having to wait for the entire response to be completed.

Unfortunately it is not possible to implement ImageInput on such a network image, because http works asynchronously. It would be really great if you could make the getRange method async and better yet create a NetworkInput class

Seconded, this would be really nice

Ya I have a use case

Now, support http_input. Use image_size_getter_http_input and read document to use it.

In addition, AsyncImageInput has been customized, which can be customized according to requirements.
