[flutter_svg] SvgNetworkLoader never closes internal HTTP client #158928
Description
Steps to reproduce
- Create a
SvgNetworkLoaderinstance, without passing it a custom http client - Call
prepareMessage(), which will create an internal client - The created client is never calling its
close()method
3a. I had hoped to demonstrate this with a test that enables leak tracking, but the HTTP client does not register itself with the memory allocations tooling
Expected results
The client is closed at the end of postMessage()
Actual results
If the SvgNetworkLoader is not provided with a client, its internal client is not cleaned up.
Code sample
Code sample
import 'package:flutter_svg/svg.dart';
void main() async {
const String url =
'https://raw.githubusercontent.com/flutter/packages/b9ac917daeb0fbf5bd6ad4a7d2a69ab81749d767/third_party/packages/flutter_svg/example/assets/flutter_logo.svg';
const SvgNetworkLoader loader = SvgNetworkLoader(url);
await loader.prepareMessage(null);
