This pull request fixes#143803 by taking advantage of Dart's null-aware operators.
And unlike `switch` expressions ([9 PRs](https://github.com/flutter/flutter/pull/143634) and counting), the Flutter codebase is already fantastic when it comes to null-aware coding. After refactoring the entire repo, all the changes involving `?.` and `??` can fit into a single pull request.
I continued [my mission](https://github.com/flutter/flutter/pull/141431) to find as many typos as I could. This time it's a smaller set than before.
There is no need for issues since it's a typo fix.
This PR includes the following changes. These changes only apply to iOS 17 physical devices.
| Command | Change Description | Changes to User Experience |
| ------------- | ------------- | ------------- |
| `flutter run --release` | Uses `devicectl` to install and launch application in release mode. | No change. |
| `flutter run` | Uses Xcode via automation scripting to run application in debug and profile mode. | Xcode will be opened in the background. Errors/crashes may be caught in Xcode and therefore may not show in terminal. |
| `flutter run --use-application-binary=xxxx` | Creates temporary empty Xcode project and use Xcode to run via automation scripting in debug and profile. | Xcode will be opened in the background. Errors/crashes may be caught in Xcode and therefore may not show in terminal. |
| `flutter install` | Uses `devicectl` to check installed apps, install app, uninstall app. | No change. |
| `flutter screenshot` | Will return error. | Will return error. |
Other changes include:
* Using `devicectl` to get information about the device
* Using `idevicesyslog` and Dart VM logging for device logs
Note:
Xcode automation scripting (used in `flutter run` for debug and profile) does not work in a headless (without a UI) interface. No known workaround.
Fixes https://github.com/flutter/flutter/issues/128827, https://github.com/flutter/flutter/issues/128531.
* setup wireless debugging to use device IP
* fix tests
* fix unused var and missing annotation
* remove unneeded try catch
* remove commented out line, change null to package id
* better way to get package id
* update mDNS lookup to continously check for server, add messaging if takes too long to find observatory url, update flutter drive to enable publish-port if using network device
* Refactor mDNS Discovery to poll for observatories and better handle multiple instances of the same app. Update drive command to make publish-port more stable. Update attach for iOS to only use Protocol Discovery if applicable, run mDNS and Protocol Discovery simultaneously, handle --debug-port/--debug-url/--device-vmservice-port, continously poll for obseravtories with mDNS, include port in error message when mutliple available
* add and update comments, use logger spinner intead of timer in flutter attach, other small improvements
* add newline to message so next log won't be on same line
* fix install/waiting for permission status progress so it doens't double print the time it took.
* only print backtrace if observatory times out on a physical usb connected device
* fix test
* Update related references from Observatory to Dart VM Service
* fix test
* add debugging options to simulator, test more debugging flags, add tests for other launch arguements
* refactor iOS launch arguments to use one function for both simulator and physical devices
* treat dart flags differently between physical and simulator
* Simplify some flags between devices.
Change --disable-service-auth-codes to not always be included for physical devices, only if disableServiceAuthCodes is true.
Change --disable-observatory-publication to be used for simulator devices too.
Change --enable-checked-mode & --verify-entry-points to be used if debuggingEnabled is true regardless of device type.
Chnage --trace-startup to be used for simulator devices too.
* fix ios release mode with buildable app startApp test
* determine observatory-port from deviceVmServicePort and hostVmServicePort
* add comments and remove hasObservatoryPort
