You can also set a breakpoint directly with [lldb](https://lldb.llvm.org/tutorial.html) by expanding **Flutter > Runner** in the Runner Project Navigator. Put a breakpoint in `AppDelegate.swift`'s `application(didFinishLaunchingWithOptions:)` (Swift project) or `main.m`'s `main()` (Objective-C project) and start the application by clicking the Run button (CMD + R). Then, set your desired breakpoint in the engine in `lldb` via `breakpoint set -...`.
