The same issue, please help us!!!!

[sumitrvi]

Hey I'm also facing same issue. please help me.

[KevMorelli]

unable to reproduce, can you test with version 0.3.0 ?

[Hasankanso]

yes it's still there, although the error message is a bit different now:

[ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: SocketException: Connection attempt cancelled, host: maps.googleapis.com, port: 443

we solved it by adding a try catch to the line 429 in src/flutter_google_places.dart:

       var res;
      try {
           res = await _places!.autocomplete(
        value,
        offset: widget.offset,
        location: widget.location,
        radius: widget.radius,
        language: widget.language,
        sessionToken: widget.sessionToken,
        types: widget.types!,
        components: widget.components!,
        strictbounds: widget.strictbounds!,
        region: widget.region,
      );
      } catch (e) {
        print(e);
      }
      if (res == null) {
        onResponse(null);
        return;
      }

again, this only happens when the search page is popped (closed) before a response is received.

This doesn't fix the error in my code. Have to get a different library.

I have updated this package, please use the following:

  flutter_google_places:
    git:
      url: https://github.com/fluttercommunity/flutter_google_places
      ref: v0.3.2

[khttps]

I have updated this package, please use the following:

  flutter_google_places:
    git:
      url: https://github.com/fluttercommunity/flutter_google_places
      ref: v0.3.2

Still got the same error after the update

Hi. I have a similar issue with my flutter app. When I call an API function, the app crashes with the error "Connection closed before full header was received" on my mobile (samsung, Android). If I connect using wifi, the call works correctly. If I use emulatores, the app works correctly too. No problems testing with postman. If I call the same code linking to another API url (but it's the same API code), I do not have any problems. Flutter doctor was ok. My mobile works correctly with any other app/request

Here's the code

Uri l_Uri = Uri.parse("http://xxxx:xxxx/api/Login");
 final response = await http.post(l_Uri,
        body: l_body,
        headers: {
          "Accept": "application/json",
          "content-type": "application/json", 
        });

where body:
 {
    "UserName": "***",
    "Password": "***",
    "SvrUsername": "***",
    "SvrPassword": "***"
}

After a few seconds, the error "Connection closed before full header was received"

Can you help me?
