logI function

void logI(Object? message, { DateTime? time, int? sequenceNumber, int level = 0, String name = '', Zone? zone, Object? error, StackTrace? stackTrace, int stackIndex = 1, })

日志打印 stackIndex 非负数时打印调用信息

Implementation

void logI(
  Object? message, {
  DateTime? time,
  int? sequenceNumber,
  int level = 0,
  String name = '',
  Zone? zone,
  Object? error,
  StackTrace? stackTrace,
  int stackIndex = 1,
}) {
  var targetLine = "";
  if (stackTrace == null && stackIndex >= 0) {
    var trace = StackTrace.current;
    var lines = trace.toString().split("\n");
    targetLine = "\n      <=${lines[1].replaceFirst("#$stackIndex      ", "")}";
  }

  if (!kDebugMode) return;
