Hex values doubled in IDA/Ghidra decompiled code

I have the following piece of dart code, which check if the input is "ABCDE" and prints correct if the input matches, and it works fine.

import 'dart:io';
final List<int> flag = [65, 66, 67, 68, 69];
void main() {
  print("\ngive flag: ");
  List<int> input = stdin.readLineSync(encoding: latin1)!.codeUnits;
  if (input.length != flag.length) {
    print("\nnot flag");
    return;
  }
  for (int i = 0; i < flag.length; i++) {
    if (input[i] != flag[i]) {
      print("\nnot flag");
      return;
    }
  }
  StringBuffer newFlag = new StringBuffer();
  input.forEach((e) {
    newFlag.writeCharCode(e);
  });
  print("correct");
}

I compiled the code with dart compile aot-snapshot exmaple.dart and then tried to decompile it with IDA and Ghidra. However, the original decimal values seem to be doubled in the decompiled code.

Ghidra decompiled code:

void flag(void)

{
  long lVar1;
  long extraout_RAX;
  long unaff_R14;
  
  if (&stack0xfffffffffffffff8 < *(undefined **)(ulong *)(unaff_R14 + 0x40) ||
      &stack0xfffffffffffffff8 == *(undefined **)(ulong *)(unaff_R14 + 0x40)) {
    (**(code **)(unaff_R14 + 0x238))();
  }
  lVar1 = Precompiled_Stub__iso_stub_AllocateArrayStub();
  *(undefined8 *)(lVar1 + 0x17) = 0x82;
  *(undefined8 *)(lVar1 + 0x1f) = 0x84;
  *(undefined8 *)(lVar1 + 0x27) = 0x86;
  *(undefined8 *)(lVar1 + 0x2f) = 0x88;
  *(undefined8 *)(lVar1 + 0x37) = 0x8a;
  new__GrowableList._withData();
  *(undefined8 *)(extraout_RAX + 0xf) = 10;
  return;
}

0x82, 0x84, 0x86, 0x88, 0x8a in decimal are 130, 132, 134, 136, 138.
The dec values are double of what was originally in the code (65, 66, 67, 68, 69). I am not sure why this is happening...

My aim is to be able to tell that "ABCDE" is the required input just by the .aot file. Thanks :)
