Uint8List是Dart中的一种无符号8位整数列表类型,它表示一个字节序列。通过将int类型的值转换为Uint8List类型,可以将整数表示为字节序列。 以下是将int转换为Uint8List的示例代码: 代码语言:txt 复制 int value = 123; Uint8List bytes = Uint8List.fromList([value]); 在上述示例中,我们首先定义一个int类型...
在OpenVPN序列化方法中，将Uint8List转换为List<int>。根据您的实现，它可能如下所示：...
要将List<int> 转换为 Uint8List,你需要确保 List<int> 中的每个元素都在 uint8 的值域内(即 0 到 255 之间)。如果超出这个范围,则需要进行适当的处理,例如截断或抛出异常。以下是一个示例代码,展示了如何实现这一转换: dart import 'dart:typed_data'; Uint8List listIntToUint8List(List...
ByteData audioByteData = await rootBundle.load(audioAssetsFullPath); Uint8List audioUint8List = audioByteData.buffer.asUint8List(audioByteData.offsetInBytes, audioByteData.lengthInBytes); List<int> audioListInt = audioUint8List.map((eachUint8) => eachUint8.toInt()).toList(); 1. 2. 3. ...

Summary:TheUint8List.fromList()constructor is significantly slower than creating aUint8Listwith a specified length and then setting each element individually. This performance difference is likely due to the wayfromList()handles copying data.
