For additional information about this feature, see +https://dart.dev/null-safety. + +The folder contains two sample Flutter apps: + + * `null_unsafe_app`: This contains a small weather app, which has three null + errors in its rendering code as a result of not using null safety. + + Try running the app (`flutter run` in a terminal, or the Run action in + VSCode/Android Studio), and see if the UI works. The null errors are + sporadic, so try hot reloading a bunch of times and experience the app + sometimes working and sometimes failing. + + * `null_safe_app`: This contains the same weather app, but this time using + null safety. There are two copies of the source code: + + `lib/badapp.dart`: This is the same source code as in the unsafe app. Try + uncommenting the two commented lines of null-unsafe code, and notice how the + Dart analyzer with null safety immediately flags the lines as unsafe. + + `lib/goodapp.dart`: This a safe version of the unsafe app, with the null + errors fixed. Read through the comments to see illustrations of how to resolve + null errors with null safety. + +## Running the example code + +Null safety is still in technical preview. As a result you need to use a +dev-channel Flutter build, and you have to pass an [experiment +flag](https://dart.dev/tools/experiment-flags). + +### Flutter SDK requirements + +This sample is +[experimental](https://github.com/flutter/samples/tree/master/experimental), and +requires using a **dev channel** Flutter SDK. You can change to the dev channel +with `flutte channel dev` followed by `flutter upgrade` (don't forget to change +back to `flutter channel stable` for production use. + +### Running from the terminal/command-prompt + +Because null safety is still in tech preview, we need to pass a so-called +_experiment flag_ when invoking any Flutter command in the terminal, which looks +like this: `--enable-experiment=non-nullable`. + +To run the main app, type these commands in the terminal/command-prompt: + + - Windows: + - `cd \experimental\null_safety\null_safe_app\` + - `flutter pub get` + - `flutter run --enable-experiment=non-nullable` + - macOS/Linux: + - `cd /experimental/null_safety/null_safe_app/` + - `flutter pub get` + - `flutter run --enable-experiment=non-nullable` + +### Running from VSCode + +This example contains a launch configuration for VSCode that passes the +experimental flag, so to run the sample in VSCode: + + 1. Invoke **File > Open**, and select the `null_safety/null_safe_app` folder. + + 1. Select **Run > Run** and the project should run and print a message in the + Debug Console. + + +### Running from Android Studio + + 1. Start Android Studio. + + 1. Select Open Project, and select the `null_safety/null_safe_app` folder. + + 1. Open the file `lib/main.dart` in the code editor. + + 1. Select Run > Run and the project should run and print a message in the Run + pane. diff --git a/experimental/null_safety/null_safe_app/.gitignore b/experimental/null_safety/null_safe_app/.gitignore new file mode 100644 index 000000000..0fa6b675c --- /dev/null +++ b/experimental/null_safety/null_safe_app/.gitignore @@ -0,0 +1,46 @@ +# Miscellaneous +*.class +*.log +*.pyc +*.swp +.DS_Store +.atom/ +.buildlog/ +.history +.svn/ + +# IntelliJ related +*.iml +*.ipr +*.iws +.idea/ + +# The .vscode folder contains launch configuration and tasks you configure in +# VS Code which you may wish to be included in version control, so this line +# is commented out by default. +#.vscode/ + +# Flutter/Dart/Pub related +**/doc/api/ +**/ios/Flutter/.last_build_id +.dart_tool/ +.flutter-plugins +.flutter-plugins-dependencies +.packages +.pub-cache/ +.pub/ +/build/ + +# Web related +lib/generated_plugin_registrant.dart + +# Symbolication related +app.*.symbols + +# Obfuscation related +app.*.map.json + +# Android Studio will place build artifacts here +/android/app/debug +/android/app/profile +/android/app/release diff --git a/experimental/null_safety/null_safe_app/.idea/codeStyles/Project.xml b/experimental/null_safety/null_safe_app/.idea/codeStyles/Project.xml new file mode 100644 index 000000000..0d156937b --- /dev/null +++ b/experimental/null_safety/null_safe_app/.idea/codeStyles/Project.xml @@ -0,0 +1,134 @@ + + + + + + + + + + + +
