flutter中对比两个数组相同
import 'package:collection/collection.dart';
Function eq = const ListEquality().equals;
print(eq([1,'two',3], [1,'two',3])); // => true
16进制打印数组
import 'package:sprintf/sprintf.dart';
static String toHexArray(List<int> tmp_rev2) {
String sb = "";
for (var value in tmp_rev2) {
sb += sprintf("%02x ",[value]);
}
return sb;
}
从a数组中查询b数组是否存在及存在的位置
static int indexOf(List<int> a, List<int> b, int offset) {
int flag = -1;
f1:
for (int i = offset; i <= a.length - b.length; i++) {
for (int i1 = 0; i1 < b.length; i1++) {
if (a[i + i1] != b[i1]) {
continue f1;
}
}
flag = i;
break;
}
return flag;
}
