Dart/Flutter 中的 TimingLogger 相当于什么？

Question

        val timings = TimingLogger("FEED_PROFILE", "reading bitmap frame")
        val bitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.size);
        timings.addSplit("converting bytes to bitmap done")
        val bmOverlay = Bitmap.createBitmap(bitmap.width, bitmap.height, bitmap.config)
        timings.addSplit("reading bitmap done")
        timings.dumpToLog()

以上打印

D/FEED_PROFILE( 5019): reading bitmap frame: begin
D/FEED_PROFILE( 5019): reading bitmap frame:      244 ms, converting bytes to bitmap done
D/FEED_PROFILE( 5019): reading bitmap frame:      0 ms, reading bitmap done
D/FEED_PROFILE( 5019): reading bitmap frame: end, 244 ms

但这是 Kotlin/Java 代码。 Flutter/Dart 需要什么才能达到类似的结果？

目前，我正在使用

 final start = DateTime.now().millisecondsSinceEpoch;
 // something
 final lapse = DateTime.now().millisecondsSinceEpoch - start;
 print('$logId Screenshoot took $lapse ms ${pngBytes.length}');

但是当我尝试复制 addSplit 时，这会变得复杂。因此，我正在寻找 Dart 或 Flutter 中内置的东西
