better_networking Package Creation

[synapsecode]

PR Description

This PR aims to separate all the networking related contents from apidash_core and instead re-package them into another public flutter package named better_networking.

This package contains all of the networking parts that apidash relies on. Including httpRequest creation, cancellation, HttpRequest & HttpResponse Models and so on

Moreover as a new feature, HTTP Streaming has been implemented with cancellation ability. This allows future expansion of apidash into Server Side Events (SSE), WebSockets and Streaming GenAI Responses

Streaming Request Example

final stream = await streamHttpRequest(
  'S1',
  APIType.rest,
  HttpRequestModel(
    method: HTTPVerb.post,
    url: 'http://localhost:11434/v1/chat/completions',
    body: jsonEncode({
      'model': 'gemma3:latest',
      'stream': true,
      "messages": [
        {
          "role": "system",
          "content":
              'Give me a 200 word essay about the given topic',
        },
        {"role": "user", "content": 'Flutter'},
      ],
    }),
  ),
);
stream.listen(
  (data) {
    print('Recieved Data: $data');
  },
  onDone: () {
    print('Streaming Complete');
  },
  onError: (e) {
    print(e);
  },
);

Cancelling Stream Request

cancelHttpRequest('S1');

import 'package:apidash_core/apidash_core.dart';

should not be replaced by

import 'package:better_networking/better_networking.dart';

apidash_core/apidash_core.dart should export 'package:better_networking/better_networking.dart'; which will make it available wherever apidash_core is imported inside apidash.

[animator]

Should not be directly added here.
better_networking will flow into apidash via apidash_core.

[synapsecode]

Hi @animator, better_networking has been exported from apidash_code and all imports have been fixed.

[animator]

Kindly make only necessary changes in the PR.
A lot of import formatting and other formatting changes have been made which is not required.

have reverted them. changed file count is down. vscode had the format on save enabled so many of the modified files got auto-formatted and didnt catch it when seeing the changes.
