Uint8List是一个无符号8位整数的列表,通常用于表示二进制数据。 2. 查找或编写一个函数,将String转换为Uint8List 在Flutter中,可以使用dart:convert库中的utf8.encode函数将String转换为Uint8List。这个函数会将字符串编码为UTF-8格式的字节数据。 dart import 'dart:convert'; Uint8List stringToUint8List(String...
这个方法有效的原因是：向容量为零的切片追加元素将分配一个新的底层数组。函数体的长度最终比函数签名的...
<uint16_t zllen> is the number of entries. When there are more than 2^16-2 entries, this value is set to 2^16-1 and we need to traverse the entire list to know how many items it holds. zllen,表示entry的数量 <uint8_t zlend> is a special entry representing the end of the zi...
