Limitations - flutter-tizen/flutter-tizen GitHub Wiki

General

• The official Flutter extension for VS Code does not support Tizen devices. You can use this workaround to debug your app using the VS Code debugger and Flutter DevTools.
• The flutter-tizen tool always depends on the latest stable version of the Flutter framework. You can use one of these tags to depend on an older version of the framework.
• Tizen devices that are not listed in #supported-devices (e.g. Family Hub) are not officially supported.
• Building a multi-arch TPK is not supported.
• Dart-to-JavaScript (exporting to the web application format) is not supported. This issue is being tracked by flutter-tizen#245.
• Hosting a native platform view (NUI or EFL widget) within a Flutter app is not currently supported. This issue is being tracked by flutter-tizen#459.
  • c.f. Hosting a Flutter view within a native platform view is already supported.
• App state restoration is not automatically done by the framework because the required functionality is not available on Tizen.

Plugins

• Not all Firebase plugins (FlutterFire) are currently available for Tizen. This issue is being tracked by flutter-tizen#353.
• Some plugins may stop working after a hot restart in background (non-root) isolates. This issue is related to flutter-tizen#516.
• The webview plugin (webview_flutter_tizen) is currently unstable and not recommended for production use.

APIs

• Some SystemChrome functions are not supported due to the platform limitations.
  • setApplicationSwitcherDescription
  • setEnabledSystemUIMode (partially supported)
  • setSystemUIOverlayStyle
• The platformBrightness property always returns Brightness.light since the platform doesn't support Dark mode.
• The Platform.isTizen property is not available from the dart:io package. You may use the isTizen property from the flutter_tizen package instead.
• Some accessibility features may not be supported on certain devices. See flutter-tizen#151 for details.
• Layout dimensions do not change when a software keyboard is shown. This issue is being tracked by flutter-tizen#70.
• Changing the appearance of the mouse cursor using SystemMouseCursors is supported on TV devices only. Only the basic, click, none, and text types are supported.

TV limitations

• Flutter apps cannot be run on 2020 or earlier TV models (Tizen 5.5 or earlier) due to Samsung TV division's security policies. More information can be found in this comment.
• For a similar reason, apps created with the --tizen-language cpp option cannot be run on TV devices.
• TV devices generally have more restrictions than other types of devices. For example, the following sdb commands are not supported by TV devices: shell, dlog, push, pull, root.
• Flutter-tizen does not provide support for the development of Smart Signage applications. While it is possible to create and test an application locally on certain devices, we do not provide support for technical issues, such as installation, debugging, and testing. For more information on signage models, please refer to Signage model groups.

Performance

• SkSL shader caching is not supported. This feature has been disabled because it significantly increases the app startup latency.
• The Tizen embedder doesn't support the Vulkan rendering backend (only supports EGL and Evas GL). This issue is being tracked by embedder#4.
• Impeller is not currently available for Tizen. This issue is being tracked by embedder#15.
