After running "workbench.extensions.installExtension", extensions.getExtension still returns undefined

[DanTup]

After installing an extension with workbench.extensions.installExtension it seems impossible to activate the extension because vs.extensions.getExtension returns undefined.

For ex:

if (res === installExtension) {
		await vs.commands.executeCommand("workbench.extensions.installExtension", flutterExtensionIdentifier);
		console.warn('...');
		console.warn(vs.extensions.getExtension(flutterExtensionIdentifier));
	}

prints:

...
undefined

@DanTup I do not think vs.extensions gets populated immediately, you have to listen to the changes on vscode.extensions.

@sandy081 Aha! I thought the command would wait for it to complete, but you're right - this seems to do the trick. Thanks!

await vs.window.withProgress({ location: vs.ProgressLocation.Notification },
	(progress) => {
		progress.report({ message: "Installing Flutter extension" });

		return new Promise((resolve) => {
			vs.extensions.onDidChange((e) => resolve());
			vs.commands.executeCommand("workbench.extensions.installExtension", flutterExtensionIdentifier);
		});
	},
);
