Dart Tone Checker

Add the http package to pubspec.yaml before running this example.

import 'dart:convert';
import 'dart:io';

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

Future<void> main() async {
  final apiKey = Platform.environment['SAPLING_API_KEY'];
  if (apiKey == null || apiKey.isEmpty) {
    throw StateError('Set SAPLING_API_KEY first.');
  }

  final response = await http.post(
    Uri.parse('https://api.sapling.ai/api/v1/tone'),
    headers: {
      HttpHeaders.authorizationHeader: 'Bearer $apiKey',
      HttpHeaders.contentTypeHeader: 'application/json',
    },
    body: jsonEncode({
      'text': 'Really stoked about this! Will it be ready by next week?',
    }),
  );

  if (response.statusCode < 200 || response.statusCode >= 300) {
    throw HttpException(
      'Sapling API error ${response.statusCode}: ${response.body}',
    );
  }

  print(const JsonEncoder.withIndent('  ').convert(jsonDecode(response.body)));
}
