Performance issue

[Tokenyet]

Recently, I used entitas_ff to play with flame, and I found out that It's expensive to use entitas_ff. According to the observatory, It seems to use too many cpu resource on single get. Is there any way to reduce cpu consumption?

class MeasurementUtil {
  static final Map<String, DateTime> timemap = {};

  static void start(String timeName) {
    timemap[timeName] = DateTime.now();
  }

  static void end(String timeName) {
    if(timemap.containsKey(timeName)) {
      print("$timeName: ${DateTime.now().difference(timemap[timeName]).inMilliseconds} ms");
      timemap.remove(timeName);
    }
  }
}

void main() {
  Map<int, int> value = {
    0: 0,
    1: 1,
    2: 2,

  Map<String, int> sValue = {
    "0": 0,

  Map<Type, int> tvalue = {
    AComp: 0,
    BComp: 1,
    CComp: 2,
    DComp: 3,
    EComp: 4,
    FComp: 5,
    GComp: 6,
    HComp: 7,
    IComp: 8,
    JComp: 9,
  };
  MeasurementUtil.start("int");
  for(int i = 0; i < 1000000;i++) {
    int c = value[0];
  }
  MeasurementUtil.end("int");
  
  MeasurementUtil.start("string");
  for(int i = 0; i < 1000000;i++) {
    int c = sValue[0];
  }
  MeasurementUtil.end("string");
  
  MeasurementUtil.start("type");
  for(int i = 0; i < 1000000;i++) {
    int c = tvalue[GComp];
  }
  MeasurementUtil.end("type");
}

int: 12 ms
string: 9 ms
type: 59 ms

I'm not sure how to optimze, but seems this is the issue of using Type as key.
