对于在iOS和Android上略有不同的UI，即在不同的平台上，必须有一种方法来检测应用程序在哪个平台上运行，但我在文档中找不到它。是什么?

所以这里有一个小工具，我用来检测平台和操作系统的反应适当。
import'dart:io' show Platform;
import 'package:flutter/foundation.dart' show kIsWeb;
class Util {
os getPlatform() {
if (kIsWeb) {
return os.Web;
} else if (Platform.isIOS) {
return os.IOS;
} else if (Platform.isAndroid) {
return os.Android;
} else if (Platform.isFuchsia) {
return os.Fuchsia;
} else if (Platform.isLinux) {
return os.Linux;
} else if (Platform.isMacOS) {
return os.MacOS;
} else if (Platform.isWindows) {
return os.Windows;
}
return os.Unknown;
}
bool isWeb() {
return (getPlatform()==os.Web);
}
bool isMobile() {
os platform = getPlatform();
return (platform == os.Android || platform == os.IOS || platform== os.Fuchsia);
}
bool isComputer() {
os platform = getPlatform();
return (platform == os.Linux || platform == os.MacOS || platform== os.Windows);
}
}
enum os { Unknown, Web, Android, Fuchsia, IOS, Linux, MacOS, Windows }
其他回答
import 'dart:io' show Platform; //at the top
String os = Platform.operatingSystem; //in your code
print(os);
Dart主机平台检查。
导入'dart:io'作为io;
_checkingHostPlatform(){
if(IO.Platform.isAndroid){
//Execute code for android
}else if(IO.Platform.isIOS){
//Execute code for iOS
}else{
//Execute code for other platforms
}
}
**multiple platform you check and run your code according specific platform **
bool isIOS = Theme.of(context).platform == TargetPlatform.iOS;
bool isAndroid = Theme.of(context).platform == TargetPlatform.android;
bool islinux = Theme.of(context).platform == TargetPlatform.linux;
bool isfuchsia = Theme.of(context).platform == TargetPlatform.fuchsia;
bool isMacOS = Theme.of(context).platform == TargetPlatform.macOS;
bool iswindows = Theme.of(context).platform == TargetPlatform.windows;

你可以这样做
defaultTargetPlatform == TargetPlatform.iOS
? kIOSTheme
: kDefaultTheme,
从导入'包:flutter/foundation.dart';
