在这个例子中,isLoggedIn是一个布尔值,决定了显示的文本内容。 1.2 使用多个条件 如果需要根据多个条件进行更复杂的判断,可以将多个if语句结合使用: @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Multi-condition Rendering Example'), ), body: Center( child:...

if用于当满足条件(结果为true)执行对应的代码块;if...else中当if条件不满足时,执行else的代码块。 boolcondition = Random().nextBool();// 单分支if(condition){// condition = true 时执行逻辑}// 二分支if(condition){// condition = true 时执行逻辑}else{// condition = false 时执行逻辑} 如果需要...

在上述代码中,"condition"是一个布尔表达式,用于判断是否执行if语句中的代码块。如果条件为真,则执行if语句中花括号内的代码块;否则,执行else语句中花括号内的代码块。 以下是一个示例,展示如何将if语句添加到main.dart文件中: 代码语言:txt 复制 import 'package:flutter/material.dart'; void main() { bool ...

since code that's tree-shaken is still type-checked, and so simply using platform-based guards in your code isn't enough if there are unrelated types involved in those guarded bits of code, even if they're consistent if you only consider a specific condition for the guards (e.g., compi...
