Problems when printing a 10e6 character String to console

What happened

(please describe what you were doing when this exception occurred)

I wrote this command below 😃 const int printableCharsStartIndex = 32; const int charLength = 1114111 - printableCharsStartIndex; final List<int> charCodes = List.generate(charLength, (index) => index+printableCharsStartIndex); final String chars = String.fromCharCodes(charCodes); print(chars.split(‘’)); FlutterClipboard.copy(chars.split(‘’).toString()).then((value) { print(‘DONE !’); });

Version information

Android Studio Bumblebee | 2021.1.1 Patch 1 • Flutter plugin io.flutter 64.1.2 • Dart plugin 211.7798

Error getting Flutter sdk information.

I wasn’t able to exactly reproduce the problem, but I did cause Android Studio to become unresponsive. I think trying to print a million-character string broke it. I did not get an exception but I had to force-quit Android Studio.

@jacob314 I’m tempted to close this issue. Is this use-case something we want to encourage? The user is using a Flutter app to print a million characters to the console in the IDE.
