CERTIFICATE_VERIFY_FAILED: self signed certificate in certificate chain(handshake.cc:354))

[qzcsfchh]

I got this problem when loading image with urls of 'https' scheme, and I've tried 'HttpOverrides' but it does'nt work, my code was like:

  HttpOverrides.runZoned(() async {
    runApp(MyApp());
  },createHttpClient: UnSafeHttpClient);

HttpClient UnSafeHttpClient(SecurityContext ctx) {
  HttpClient client = HttpClient();
  client.badCertificateCallback = (cert, host, port) => true;
  return client;
}

What can I do to solve this pronlem?

Haven't tried it, but maybe this works?

If that doesn't work you can also supply your own FileFetcher to the CacheManager. The default one is just this:

      {Map<String, String> headers}) async {
    var httpResponse = await http.get(url, headers: headers);
    return new HttpFileFetcherResponse(httpResponse);
  }```
You can easily copy/paste the DefaultCacheManager code and add some logic for this.

Note that the API for the FIleFetcher will completely change in the next major release. See the development branch of the current state.
