name Flutter Attach to Device type dart request attach

This is a configuration for debugging Flutter apps using Visual Studio Code. It specifies that the debugger should attach to a running device or emulator and listen for any debugging events. The "name" field is a user-defined name for this configuration, while the "type" field specifies that this configuration is for debugging Dart code. The "request" field specifies that the debugger should attach to a running process rather than starting a new process.
