getsentry/sentry-flutter-sdk

Configuração completa do SDK do Sentry para Flutter e Dart. Use quando precisar 'adicionar Sentry ao Flutter', 'instalar sentry_flutter', 'configurar Sentry no Dart' ou implementar monitoramento de erros, rastreamento, perfilamento, replay de sessão ou registro de logs para aplicativos Flutter. Compatível com Android, iOS, macOS, Linux, Windows e Web.

O que é sentry-flutter-sdk?

Esta skill automatiza a configuração do Sentry SDK em projetos Flutter e Dart, fornecendo uma integração completa para monitoramento de erros e desempenho. Ela instala o pacote `sentry_flutter` (ou `sentry` para Dart puro) e configura recursos essenciais como rastreamento de exceções, transações de desempenho (tracing), perfilamento de código, replay de sessão e registro de logs. A skill é particularmente útil para desenvolvedores que desejam implementar rapidamente observabilidade em aplicações multiplataforma (Android, iOS, Web, desktop). Durante a configuração, ela solicita o DSN (Data Source Name) do projeto Sentry e ajusta automaticamente o arquivo `pubspec.yaml` e a inicialização no código Dart. Suporta configurações avançadas como filtros de erros, amostragem de transações e integração com frameworks como BLoC ou Riverpod, seguindo as melhores práticas de desempenho e segurança. Ideal para equipes que precisam de uma configuração consistente e rápida do Sentry em pipelines CI/CD ou durante o desenvolvimento local.

O que sentry-flutter-sdk faz?

Configuração completa do SDK do Sentry para Flutter e Dart. Use quando precisar 'adicionar Sentry ao Flutter', 'instalar sentry_flutter', 'configurar Sentry no Dart' ou implementar monitoramento de erros, rastreamento, perfilamento, replay de sessão ou registro de logs para aplicativos Flutter. Compatível com Android, iOS, macOS, Linux, Windows e Web.

Funcionalidades

  • Monitoramento de Erros: Capture exceções não tratadas e erros de framework
  • Rastreamento de Desempenho: Meça tempos de carregamento, chamadas de API e navegação entre telas
  • Perfilamento de Código: Identifique gargalos de desempenho com perfis de CPU
  • Replay de Sessão: Grave e reproduza interações do usuário para depuração
  • Registro de Logs: Envie logs estruturados com níveis de severidade (debug, info, warning, error)

Requisitos

  • Flutter SDK >= 3.0.0
  • Conta no Sentry.io com projeto criado
  • DSN do projeto (pode ser obtido em Settings → Projects → Client Keys)

Instalação

Adicione o pacote ao arquivo pubspec.yaml:

dependencies:
  sentry_flutter: ^8.0.0

Ou para projetos Dart puro (sem Flutter):

dependencies:
  sentry: ^8.0.0

Configuração Inicial

No arquivo principal (main.dart), inicialize o Sentry antes de rodar o aplicativo:

import 'package:flutter/material.dart';
import 'package:sentry_flutter/sentry_flutter.dart';

Future<void> main() async {
  await SentryFlutter.init(
    (options) {
      options.dsn = 'https://[email protected]/0';
      options.tracesSampleRate = 1.0; // Ajuste entre 0.0 e 1.0
      options.profilesSampleRate = 1.0; // Ativar perfilamento (requer plano Business)
      options.enableUserInteractionBreadcrumbs = true; // Rastrear toques e gestos
      options.enableOutOfMemoryTracking = true; // Monitorar falta de memória
      options.attachScreenshot = true; // Anexar screenshot em erros (apenas iOS/Android)
    },
    appRunner: () => runApp(MyApp()),
  );
}

Uso Avançado

Capturar Erros Manualmente

try {
  throw Exception('Erro personalizado');
} catch (exception, stackTrace) {
  await Sentry.captureException(exception, stackTrace: stackTrace);
}

Criar Transações Personalizadas

import 'package:sentry/sentry.dart';

final transaction = Sentry.startTransaction(
  'process-order',
  'task',
  bindToScope: true,
);

try {
  // Lógica da transação
} finally {
  transaction.finish();
}

Configurar Amostragem

options.tracesSampler = (samplingContext) {
  if (samplingContext.customSamplingContext['url']?.contains('/health') == true) {
    return 0.0; // Não amostrar endpoints de health check
  }
  return 0.2; // 20% das transações
};

Integração com BLoC

import 'package:sentry_flutter/sentry_flutter.dart';

// No construtor do BLoC
Sentry.addBreadcrumb(Breadcrumb(
  message: 'BLoC criado',
  category: 'bloc',
  level: SentryLevel.info,
));

Solução de Problemas

  • Erro "DSN inválido": Verifique se o DSN está correto no formato https://[email protected]/YYY
  • Perfis não aparecem: Ative o perfilamento nas configurações do projeto no Sentry.io e defina profilesSampleRate > 0
  • Sessões não gravadas: Certifique-se de que enableAutoSessionTracking não foi desabilitado (padrão: ativado)
