Comment

Removing some required parameters and adding null checks resolved my issue

import 'package:http/http.dart' as http;
import 'package:http/http.dart';

class CustomHttpClient extends http.BaseClient {
  final Map<String, String> _defaultHeaders = {};
  final http.Client _httpClient = http.Client();
  
  @override
  Future<http.StreamedResponse> send(http.BaseRequest request) {
    return _httpClient.send(request);
  }

  @override
  Future<Response> get(Uri url, {Map<String, String>? headers}) => _httpClient
      .get(url, headers: _mergedHeaders(headers!))
      .timeout(const Duration(seconds: responseTimeoutSeconds));

  @override
  Future<Response> post(url,
          {Map<String, String>? headers, dynamic body, Encoding? encoding}) =>
      _httpClient.post(url,
          headers: _mergedHeaders(headers!), body: body, encoding: encoding);

  @override
  Future<Response> patch(url,
          {Map<String, String>? headers, dynamic body, Encoding? encoding}) =>
      _httpClient.patch(url,
          headers: _mergedHeaders(headers!), body: body, encoding: encoding);

  @override
  Future<Response> put(url,
          {Map<String, String>? headers, dynamic body, Encoding? encoding}) =>
      _httpClient.put(url,
          headers: _mergedHeaders(headers!), body: body, encoding: encoding);

  @override
  Future<Response> head(url, {Map<String, String>? headers}) =>
      _httpClient.head(url, headers: _mergedHeaders(headers!));

  Map<String, String> _mergedHeaders(Map<String, String> headers) =>
      {..._defaultHeaders, ...headers};
}
