Usage

Initialize ApiService

To use ApiService, you need to initialize an instance of the ApiService class with the base URL of the API you want to interact with.

import 'package:api_service/api_service.dart';

void main() {
  final apiService = ApiService(baseUrl: 'https://api.example.com');
}

Using HTTP Methods

Here’s how to use the different HTTP methods supported by api_service:

GET Request

final response = await apiService.get('/users');
if (response.statusCode == 200) {
  // Successful response
  print('Response: ${response.body}');
} else {
  // Handle error
  print('Error: ${response.statusCode}');
}

POST Request

final response = await apiService.post(
  '/users',
  body: {
    'name': 'John Doe',
    'email': 'john@example.com',
  },
);
if (response.statusCode == 201) {
  // Data successfully created
  print('Created: ${response.body}');
} else {
  // Handle error
  print('Error: ${response.statusCode}');
}

PUT Request

final response = await apiService.put(
  '/users/1',
  body: {
    'name': 'John Doe Updated',
    'email': 'john_updated@example.com',
  },
);
if (response.statusCode == 200) {
  // Data successfully updated
  print('Updated: ${response.body}');
} else {
  // Handle error
  print('Error: ${response.statusCode}');
}

DELETE Request

final response = await apiService.delete('/users/1');
if (response.statusCode == 200) {
  // Data successfully deleted
  print('Deleted: ${response.body}');
} else {
  // Handle error
  print('Error: ${response.statusCode}');
}

Error Handling

api_service automatically handles common HTTP status codes and throws exceptions based on the error type.

Example error handling:

try {
  final response = await apiService.get('/users');
  // Handle successful response
} catch (e) {
  print('Error occurred: $e');
}

Handled Exceptions:

• BadRequestException
• UnauthorizedException
• ForbiddenException
• NotFoundException
• InternalServerErrorException
• ApiException
