使用
jdLog('iap 开始订阅 -------->');
控制台打印
flutter: [ios_pay.dart line:89] iap 开始订阅 -------->
下面文件直接复制过去就能用
import 'package:flutter/foundation.dart';
void jdLog(Object log, {bool showLine = true}) {
if (kDebugMode) {
if (showLine) {
JDCustomTrace programInfo = JDCustomTrace(StackTrace.current);
print("[${programInfo.fileName} line:${programInfo.lineNumber}] $log");
} else {
print("$log");
}
}
}
class JDCustomTrace {
final StackTrace? _trace;
String fileName = '';
int lineNumber = 0;
JDCustomTrace(this._trace) {
_parseTrace();
}
void _parseTrace() {
var traceString = _trace.toString().split("\n")[1];
var indexOfFileName = traceString.indexOf(RegExp(r'[A-Za-z_]+.dart'));
var fileInfo = traceString.substring(indexOfFileName);
List listOfInfo = fileInfo.split(":");
if (listOfInfo.length >= 2) {
fileName = listOfInfo[0];
lineNumber = int.parse(listOfInfo[1]);
}
}
}
