Question

the last time when I tried to create a new flutter project, that problem appear to me

The semaphore timeout period has expired.
pub get failed
command: "C:\src\flutter\bin\cache\dart-sdk\bin\dart __deprecated_pub --directory packages\flutter_tools get --example"
pub env: {
  "FLUTTER_ROOT": "C:\src\flutter",
  "PUB_ENVIRONMENT": "flutter_cli:get",
  "PUB_CACHE": "C:\Users\ahmed\AppData\Local\Pub\Cache",
}
exit code: 69

#0      throwToolExit (package:flutter_tools/src/base/common.dart:10:3)
