Visão geral do pacote

Orientação gerada a partir de informações públicas. Apenas para referência.

Um plugin Flutter que permite armazenamento persistente simples de pares chave-valor entre plataformas. Ele abstrai APIs nativas — NSUserDefaults no iOS e SharedPreferences no Android — fornecendo uma interface unificada para armazenar dados básicos como preferências do usuário, configurações ou tokens de sessão. O pacote suporta todas as principais plataformas, incluindo Web, macOS, Windows e Linux, tornando-o ideal para persistência de dados leve e multiplataforma. Os dados são armazenados localmente e acessados de forma assíncrona, garantindo desempenho e confiabilidade em cenários típicos de aplicativos.

Casos de uso

  • Armazenando preferências do usuário
  • Salvar configurações do aplicativo
  • Persistir o estado de login
  • Armazenar em cache pequenas quantidades de dados
  • Rastrear sessões de usuário

Principais recursos

  • Compatibilidade multiplataforma
  • API simples de chave-valor
  • Operações assíncronas
  • Armazenamento local persistente
  • Suporta múltiplas plataformas

Indicado para

  • Armazenamento de dados leve
  • Gerenciamento de preferências do usuário
  • Configuração do aplicativo
  • Persistência de estado entre lançamentos
  • Necessidades simples de cache

Considerações

  • Não adequado para grandes conjuntos de dados
  • Sem capacidade de consulta
  • Os dados não são criptografados por padrão
  • Limitado a tipos primitivos
  • Não projetado para estruturas de dados complexas
