Flutter launchUrl не запускается, несмотря на то, что canLaunchUrl возвращает true в приложении Linux Ubuntu 20.04 ⇐ Linux

[Anonymous]

Я пытаюсь запустить URL-адрес с помощью кнопки на Flutter (стабильный канал, 3.16.4, в Ubuntu 20.04.6 LTS 5.15.0-122-generic, локаль en_US.UTF-8) для приложения Linux. Проверка canLaunchUrl проходит, но URL-адрес в моем браузере фактически не запускается.
Я пробовал переустановить vscode, flutter SDK, изменить сети и переключиться на устаревшие функции запуска и canLaunch. В настоящий момент я пытаюсь жестко закодировать Google в качестве URL-адреса.
