3 ## Steps to build `agl-ivi-demo-platform-flutter` image
6 export AGL_TOP=$HOME/workspace_agl
7 mkdir -p $AGL_TOP && cd $AGL_TOP
8 repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo -b master
10 source meta-agl/scripts/aglsetup.sh -m qemux86-64 agl-demo
11 bitbake agl-ivi-demo-platform-flutter
14 This builds AGL demo image that includes Flutter runtime={debug,profile,release}.
17 ## Steps to build a minimal flutter image
20 export AGL_TOP=$HOME/workspace_agl
21 mkdir -p $AGL_TOP && cd $AGL_TOP
22 repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo -b master
23 repo sync -j `grep -c ^processor /proc/cpuinfo`
24 source meta-agl/scripts/aglsetup.sh -m qemux86-64 agl-devel agl-flutter
25 bitbake agl-image-flutter
27 * includes Flutter engine runtime={debug,release,profile}
28 * includes Flutter Engine SDK
30 * live debugging/profiling with target via host
35 If recipe `flutter-engine-sdk-dev` is included in your AGL image, `engine_sdk.zip` will be present in `/usr/share/flutter/`.
37 engine_sdk.zip contains
38 * sdk/flutter_sdk.version - The Flutter SDK version
39 * sdk/engine.version - The git commit of the Flutter Engine
40 * sdk/clang_x64/gen_snapshot - used for creating release/profile AOT image
42 This recipe should be excluded from image in a production release.
45 ## Flutter Workspace Automation
49 ln -sf external/workspace-automation/flutter_workspace.py meta-agl-devel/meta-agl-flutter/tools/flutter_workspace.py
50 cd meta-agl-devel/meta-agl-flutter/tools
51 export FLUTTER_WORKSPACE=`pwd`
55 Additional documentation available [here](https://github.com/meta-flutter/meta-flutter/tree/kirkstone/tools#flutter-workspace-automation)
60 This layer includes an example systemd user service for the Flutter Gallery application which is disabled by default. It can be used to start the application in the minimal image by doing 'systemctl start flutter-gallery'.
63 ## `/usr/share/flutter/default.json`
65 For more JSON key value options see [here](https://github.com/toyota-connected/ivi-homescreen/blob/agl/README.md#json-configuration-keys)
72 This is a desktop build of flutter-auto. The default configuration for backend is set to `egl` backend. To change this to use the `vulkan` backend, change the `backend` key value in `meta-agl-flutter/tools/flutter_workspace_config.json` from `egl` to `vulkan`. If you use the workspace configuration from meta-flutter it defaults to `vulkan`.
74 If you are running a Gnome Display Manager (GDM) Wayland session, then it will be an available custom-device platform. To enable a Wayland session, you select the gear icon at the login window. If you don't have a gear icon available on your login screen, then you will need to adjust your system settings to enable a Wayland session.
76 Append `--device-id=desktop-auto` to `flutter <cmd>` to select this device.
80 This is a QEMU minimal Flutter image as referenced [here](#steps-to-build-a-minimal-flutter-image). The required runtime packages are installed as part of setup_flutter_workspace.py.
82 If qemu_run was sucessfully invoked, then this platform will be an available `custom-device`. If QEMU instance is not running on port 2222, then this custom-device platform will not be available.
84 Append `--device-id=AGL-qemu` to `flutter <cmd>` to select this device.
88 To enable local build of Flutter Engine set `tools/configs/flutter-engine.json` load key to true.
90 This enables debugging as custom engine development.
92 ## Steps to Test Flutter Images
96 1. Set up Flutter Workspace per [Flutter Workspace Automation](#flutter-workspace-automation).
98 2. Run the following commands on the host's terminal, a QEMU window and a new terminal for AGL will be brought up.
101 cd $FLUTTER_WORKSPACE
102 source ./setup_env.sh
106 3. If running an updated QEMU image, edit `~/.ssh/known_hosts` and remove previous connection.
108 4. Wait for QEMU image to boot to idle the run
110 ssh -p 2222 root@localhost who
112 _Answering with `y` appends QEMU connection to `~/.ssh/known_hosts`_
114 5. From the same host terminal open Visual Studio Code Select
116 * **gallery(AGL-qemu)** from the drop down combo box
117 * **run** - this launches the Flutter gallery app in the QEMU window
119 6. Or run from the same terminal as qemu_run was executed via
121 cd $FLUTTER_WORKSPACE/app/gallery
122 flutter run --device-id=AGL-qemu
126 ### Working with QEMU images
128 1. Setup the flutter workspace.
130 source ${FLUTTER_WORKSPACE}/setup_env.sh
132 The stdout tail should look similar to:
134 ********************************************
135 * Type 'run-agl-qemu-master' to start
136 ********************************************
137 ********************************************
138 * Type 'run-agl-qemu-octopus' to start
139 ********************************************
141 3. Select image to run using one of above commands.
147 4. If running an updated QEMU image, edit `~/.ssh/known_hosts` and remove previous connection.
149 5. Login AGL as `root`, and execute `passwd -d agl-driver`. Type `exit` and login as `agl-driver`. Run the Flutter Gallery example with the command in AGL's terminal.
152 cd $FLUTTER_WORKSPACE/app/gallery
153 flutter run -d agl-qemu-octopus
159 1. Setup the flutter workspace.
161 source ${FLUTTER_WORKSPACE}/setup_env.sh
163 The stdout tail should look similar to:
165 ********************************************
166 * Type 'run-agl-qemu-master' to start
167 ********************************************
168 ********************************************
169 * Type 'run-agl-qemu-octopus' to start
170 ********************************************
172 3. Select image to run using one of above commands.
178 4. If running an updated QEMU image, edit `~/.ssh/known_hosts` and remove previous connection.
180 5. After waiting for QEMU image to boot to idle issue
182 ssh -p 2222 root@localhost who
184 Answering with `y` appends QEMU connection to `~/.ssh/known_hosts`
186 6. Login AGL as `agl-driver`, and issue the following command
188 flutter-auto --window-type="BG" --b=/usr/share/flutter/gallery/3.3.7/profile --f --observatory-host=0.0.0.0 --observatory-port=1234
191 The last line of the output message should look similar to this:
193 flutter: The Dart VM service is listening on http://0.0.0.0:1234/xxxxxxxxxxx=/
196 7. Run the following command in the host terminal, using the correct hash suffix.
198 flutter attach --device-id=AGL-qemu --debug-url=http://127.0.0.1:1234/xxxxxxxxxxx=/
201 8. Then you should see the output as below. It tells us the URL of the Flutter DevTools debugger and profiler on AGL x86_64 QEMU Image.
202 `An Observatory debugger and profiler on AGL x86_64 QEMU Image is available at: http://127.0.0.1:37383/xxxxxxxxxxx=/`
204 9. in the terminal type `v` to launch the debugger.
