Allow setting environment variables in flutterflutterCustomEmulators

Launching the android emulator under arch linux, wayland and the sway wm results in it hanging for a minute and then failing to start with an error message : Failed to launch Pixel: Error: Emulator didn't connect within 60 seconds. starting the emulator from the terminal by $ /opt/android-sdk/emulator/emulator @flutter_emulator and seeing the error message

I have the following in my environment file to make QT applications launch under wayland QT_QPA_PLATFORM=wayland. in order to make the android emulator work i have to prefix the emulator command with a env variable override like so env QT_QPA_PLATFORM=xcb /opt/android-sdk/emulator/emulator @flutter_emulator or simply just QT_QPA_PLATFORM=xcb /opt/android-sdk/emulator/emulator @flutter_emulator how can i make the dart extension launch the emulator with this override? what i tried : in my settings.json of vscode

"dart.flutterCustomEmulators": [
        {
            "id": "flutter_emulator",
            "name": "Pixel",
            "executable": "QT_QPA_PLATFORM=xcb /opt/android-sdk/emulator/emulator",
        }
    ]

and

        {
            "id": "flutter_emulator",
            "name": "Pixel",
            "executable": "/opt/android-sdk/emulator/emulator",
            "args":["QT_QPA_PLATFORM=xcb "]
        }
    ]

both didn’t work. and the second attempt i knew was not going to work as the env override needs to happen at the begining of the command. could a way be provided to pass env variables overrides to the custom emulator configuration ?

Hello @hossamdash and @DanTup !

I also run Manjaro with Sway, and have your problem, but I tried your settings and it did not work at all. I tried:

    "dart.env": 
    {
        "_JAVA_AWT_WM_NONREPARENTING": 1,
        "QT_QPA_PLATFORM": "xcb"
    },
    "dart.flutterCustomEmulators": 
    [
        {
            "id": "Pixel_2_API_29",
            "name": "Pixel 2 API 29",
            "executable": "QT_QPA_PLATFORM=xcb _JAVA_AWT_WM_NONREPARENTING=1 /home/gusbemacbe/Android/SDK/emulator/emulator",
            "args": 
            [
                "-avd",
                "@Pixel_2_API_29"
            ]
        }
    ],

Or

    "dart.flutterCustomEmulators": 
    [
        {
            "id": "Pixel_2_API_29",
            "name": "Pixel 2 API 29",
            "env": "QT_QPA_PLATFORM=xcb _JAVA_AWT_WM_NONREPARENTING=1 /home/gusbemacbe/Android/SDK/emulator/emulator -avd @Pixel_2_API_29"
        }
    ],

@gusbemacbe you need to put them in the env key, something like this:

"dart.flutterCustomEmulators": [
	{
		"id": "Pixel_2_API_29",
		"name": "Pixel 2 API 29",
		"executable": "/home/gusbemacbe/Android/SDK/emulator/emulator",
		"args": [
			"-avd",
			"@Pixel_2_API_29"
		],
		"env": {
			"QT_QPA_PLATFORM": "xcb",
			"_JAVA_AWT_WM_NONREPARENTING": "1"
		}
	}
],
