Atualizar um card de configuração

Programa Gemini Alpha:o recurso Fluxos está disponível como parte do programa Gemini Alpha.

Este guia explica como atualizar dinamicamente um card de configuração em resposta a ações do usuário, como clicar em um botão ou selecionar um item em um menu.

Você pode inserir, remover ou substituir seções de cards e widgets para criar interfaces responsivas que se adaptam à entrada do usuário. Por exemplo, é possível atualizar uma interface de card para mostrar uma mensagem de erro de validação aos usuários que inserem uma string em um campo de entrada que espera um número inteiro e, em seguida, atualizar novamente para ocultar a mensagem depois que o usuário inserir um número inteiro.

Modificar seções e widgets de cards

Para atualizar um card, a ação do widget (como onClickAction) precisa chamar uma função que retorne um objeto RenderActions com instruções de modificação.

Nas seções de cards, é possível fazer as seguintes modificações:

• Inserir uma seção:adicione uma seção à parte de cima do card ou abaixo de uma seção especificada por ID com setInsertSection.
• Remover uma seção:remova uma seção especificada por ID com setRemoveSection.
• Substituir uma seção:substitua uma seção atual por uma nova especificada por ID com setReplaceSection.

Nos widgets de card, é possível fazer as seguintes modificações:

• Inserir um widget:adicione um widget antes ou depois de um widget especificado por ID com setInsertWidget.
• Remover um widget:remova um widget especificado por ID com setRemoveWidget.
• Substituir um widget:substitua um widget atual por um novo com setReplaceWidget.

Exemplo: inserir e remover seções e widgets

O exemplo a seguir cria um card de configuração com botões que chamam funções para modificar o card inserindo ou removendo widgets e seções.
