- 服务端: 桌面端连接/重连时全屏 ANSI 重绘; 惰性语义快照(仅移动端订阅时生成); Ping/Pong 心跳
- 桌面端: 输入改二进制帧无损透传; 指数退避自动重连; token 输入框; resumed 状态展示
- 移动端: 修复 client=mobile 参数(此前永远收不到快照); 新增最小验证 App(连接/快照显示/输入/Keybar); 支持 token; Android 网络权限
- 测试: 修正 e2e onReady 签名; 新增移动端 widget 测试

+# This file configures the analyzer, which statically analyzes Dart code to
+# check for errors, warnings, and lints.

+# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
+# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
+# invoked from the command line by running `flutter analyze`.
+
+# The following line activates a set of recommended lints for Flutter apps,
+# packages, and plugins designed to encourage good coding practices.

+  # The lint rules applied to this project can be customized in the
+  # section below to disable rules from the `package:flutter_lints/flutter.yaml`
+  # included above or to enable additional rules. A list of all available lints
+  # and their documentation is published at https://dart.dev/lints.
+  #
+  # Instead of disabling a lint rule for the entire project in the
+  # section below, it can also be suppressed for a single line of code
+  # or a specific dart file by using the `// ignore: name_of_lint` and
+  # `// ignore_for_file: name_of_lint` syntax on the line or in the file
+  # producing the lint.
