writeFile和writeText一样,都是复制String类型,虽然名称叫writeFile,但是在我们自己开发的软件中一般用不到,所以复制文件我们直接使用系统的就行。 以下是粘贴文件的代码: void_pastText()async{finalresults =awaitPasteboard.files();if(results.isNotEmpty) { _text ='';for(finalresultinresults) { _text +=...
Future<void> _writeData() async { final _dirPath = await _getDirPath(); final _myFile = File('$_dirPath/data.txt'); // If data.txt doesn't exist, it will be created automatically await _myFile.writeAsString(_textController.text); _textController.clear(); } @override Widget build...

对象序列化是将一个实现了NSCoding协议的对象,通过序列化(NSKeydArchiver)的形式,将对象中的属性抽取出来,转化成二进制流,也就是NSData,NSData可以选择write to file 或者存储到NSUserdefault中。 必须实现的两个方法 encodeWithCoder,initWithCoder。对象序列化的本质就是 对象NSData。 SQLite: 适合大量,重复,有规律...
