|
||||
|
||||
## 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 `flutter 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 <folder with samples repo>\experimental\null_safety\null_safe_app\`
|
||||
- `flutter pub get`
|
||||
- `flutter run --enable-experiment=non-nullable`
|
||||
- macOS/Linux:
|
||||
- `cd <folder with samples repo>/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.
|
||||
requires using a **beta channel** Flutter SDK. You can change to the beta
|
||||
channel with `flutter channel beta` followed by `flutter upgrade` (don't forget
|
||||
to change back to `flutter channel stable` for production use.
