领域：在android中创建导致崩溃（react-native）答案

【问题标题】：Realm: create causing a crash within android (react-native)领域：在android中创建导致崩溃（react-native）
【发布时间】：2022-06-22 00:25:50
【问题描述】：

下面的示例在使用 React Native Debugger 启用调试时工作正常，但应用程序仅在 Android 的正常模式下崩溃。有人可以帮我解决这个问题吗？

  const Cat = {
    name: "Cat",
    properties: {
      _id: "string",
      name: "string",
      age: "int",
      type: "string",
    },
  };



    const db = await Realm.open({
    schema: [Cat],
    schemaVersion: 1,
    });
    
      const cats = db.objects("Cat");
      console.log(`There are ${cats.length} cats`);
    
      db.write(() => {
    
         db.create("Cat", {  // this step is causing the crash
          _id: '1',
          name: "Alice",
          age: 14,
          type: "Calico",
        });
      });

【问题讨论】：

请通过逐行检查您的代码来执行一些故障排除，以确定哪一行正在崩溃并使用该信息更新问题。同时，检查你的 var 和代码流，直到你发现错误的地方，比如 nil var。
