DTC Lookup API - Dart/Flutter Client

DTC Lookup explains OBD-II diagnostic trouble codes such as P0301 or U0100. It returns the code's system and standard title, which warning light it turns on, and on paid plans the full description, likely causes ranked by likelihood, symptoms, repair difficulty, estimated cost and labor hours, and related codes. Carmaker-specific codes are covered for 32 makes.

This is the Dart/Flutter client for the DTC Lookup API.

Installation

Add this to your pubspec.yaml:

dependencies:
  apiverve_dtclookup: ^1.2.3

Then run:

dart pub get
# or for Flutter
flutter pub get

Usage

import 'package:apiverve_dtclookup/apiverve_dtclookup.dart';

void main() async {
  final client = DtclookupClient('YOUR_API_KEY');

  try {
    final response = await client.execute({
      'code': 'P0301',
      'make': 'Ford',
      'lang': 'en'
    });

    print('Status: ${response.status}');
    print('Data: ${response.data}');
  } catch (e) {
    print('Error: $e');
  }
}
