VSCode GDB调试控制台报错"-var-create: unable to create variable object"

背景

在使用 Visual Studio Code (1.97.2) 进行 GDB 调试时，想使用 x 命令看一下某地址处的数值。出现如下报错：

-var-create: unable to create variable object

1	-var-create: unable to create variable object

解决方案

其实，在刚刚开始调试程序时，就以黄色字体给出了解决方案。

Execute debugger commands using "-exec <command>", for example "-exec info registers" will list registers in use (when GDB is the debugger)

1	Execute debugger commands using "-exec <command>", for example "-exec info registers" will list registers in use (when GDB is the debugger)

也就是说：

如果是想查看某个变量的值，直接在输入框里输入变量名就好了；
如果要执行GDB命令，则需要加-exec前缀，如下图：

解决在macOS上使用Flutter项目访问网络报错 "SocketException: Connection failed (OS Error: Operation not permitted, errno = 1)"

在Flutter应用中添加网络支持是一个非常常见的需求。

这主要是按照以下步骤进行。

从pub.dev中安装一个网络包，如http或dio
在您的 Flutter 应用程序中添加所有必要的网络代码
如果需要，添加任何所需的API密钥

但是，如果你在macOS上运行该应用程序，你会被这个可怕的错误所欢迎。

SocketException错误已经来拜访你了

这就是它，以更可读的格式。

DioError (DioError [DioErrorType.other]: SocketException: Connection failed (OS Error: Operation not permitted, errno = 1), address = api.themoviedb.org, port = 443
Source stack:
#0      DioMixin.fetch (package:dio/src/dio_mixin.dart:488:35)
#1      DioMixin.request (package:dio/src/dio_mixin.dart:483:12)
#2      DioMixin.get (package:dio/src/dio_mixin.dart:61:12)
#3      DioHttpService.get (package:movies_app/core/services/http/dio_http_service.dart:47:35)

DioError (DioError [DioErrorType.other]: SocketException: Connection failed (OS Error: Operation not permitted, errno = 1), address = api.themoviedb.org, port = 443

Source stack:

#0 DioMixin.fetch (package:dio/src/dio_mixin.dart:488:35)

#1 DioMixin.request (package:dio/src/dio_mixin.dart:483:12)

#2 DioMixin.get (package:dio/src/dio_mixin.dart:61:12)

#3 DioHttpService.get (package:movies_app/core/services/http/dio_http_service.dart:47:35)

所以，让我们弄清楚为什么会发生这种情况，以及如何修复它。👇

注意：如果你要给一个旧的Flutter应用添加macOS支持，你可能需要运行flutter create --platforms macos . ，把macOS添加为构建目标。我在macOS上运行我的大部分应用程序，所以在构建响应式UI时，我可以轻松地调整窗口的大小。

macOS上的客户端联网权限

macOS应用程序默认为沙盒，如果你没有添加所需的权限，就会发生SocketException 的错误。

要解决这个问题，请打开名为macos/Runner/DebugProfile.entitlements 的文件并添加以下内容。

<key>com.apple.security.network.client</key>
<true/>

1 2	<key>com.apple.security.network.client</key> <true/>

然后，打开macos/Runner/Release.entitlements ，做同样的事情。

那么iOS呢？

在iOS上，只要你连接到一个安全的https 终端，该应用就可以正常运行（不需要额外的配置）。

但请记住，在某些情况下，你可能需要定制应用程序的传输安全设置，如这里所解释的。

NSAppTransportSecurity | developer.apple.com

安卓的情况如何？

在安卓系统中，曾经需要在AndroidManifest.xml 文件中添加INTERNET权限。

<uses-permission android:name="android.permission.INTERNET" />

1	<uses-permission android:name="android.permission.INTERNET" />

但根据这个答案，现在已经不需要了，因为大多数应用程序都需要互联网访问。

如何解决 "SocketException:连接失败（操作不允许）"，在macOS上使用Flutter

Error: Gradle build failed to produce an .apk file. It's likely that this file was generated under /xxxx/build, but the tool couldn't find it.

Flutter 升级到 3.27.3 版本，然后升级 Android 构建工具到最新的 AGP 8.8.0 版本，然后编译报错：

Launching lib/main.dart on sdk gphone64 arm64 in debug mode...
Running Gradle task 'assembleDebug'...
Error: Gradle build failed to produce an .apk file. It's likely that this file was generated under /xxxx/build, but the tool couldn't find it.

Running Gradle task 'assembleDebug'...

Error: Gradle build failed to produce an .apk file. It's likely that this file was generated under /xxxx/build, but the tool couldn't find it.

于是在项目的配置文件中寻找配置 "build" 目录的地方，于是在 Flutter 项目的 Android 工程根目录下找到，如下：

buildscript {
    ext.kotlin_version = '1.9.22'
    repositories {
        maven { url "https://maven.aliyun.com/nexus/content/groups/public/" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:8.8.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url "https://maven.aliyun.com/nexus/content/groups/public" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }
        google()
        mavenCentral()
    }
}

getLayout().setBuildDirectory('../build')

subprojects {
    getLayout().setBuildDirectory("${getLayout().getBuildDirectory()}/${project.name}")
}

subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete getLayout().getBuildDirectory()
}

buildscript {

ext.kotlin_version = '1.9.22'

repositories {

maven { url "https://maven.aliyun.com/nexus/content/groups/public/" }

maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }

google()

mavenCentral()

}

dependencies {

classpath 'com.android.tools.build:gradle:8.8.0'

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

}

allprojects {

repositories {

maven { url "https://maven.aliyun.com/nexus/content/groups/public" }

maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }

google()

mavenCentral()

}

getLayout().setBuildDirectory('../build')

subprojects {

getLayout().setBuildDirectory("${getLayout().getBuildDirectory()}/${project.name}")

}

subprojects {

project.evaluationDependsOn(':app')

}

tasks.register("clean", Delete) {

delete getLayout().getBuildDirectory()

}

注意 getLayout().setBuildDirectory('../build') ，以前的 Gradle 版本是可以正常编译的，现在的版本需要需要改为 rootProject.buildDir = "../build" 。

修改后的结果如下：

buildscript {
    ext.kotlin_version = '1.9.22'
    repositories {
        maven { url "https://maven.aliyun.com/nexus/content/groups/public/" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:8.8.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url "https://maven.aliyun.com/nexus/content/groups/public" }
        maven { url "https://maven.aliyun.com/nexus/content/repositories/google" }
        google()
        mavenCentral()
    }
}

rootProject.buildDir = "../build"

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}

subprojects {
    project.evaluationDependsOn(":app")
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir

Flutter各版本对操作系统的支持情况

Flutter 3.3

32-bit iOS deprecation

As we announced earlier with the 3.0 stable release, due to decreased usage, that release was the last one to support 32-bit iOS devices and iOS versions 9 and 10. This change affects the iPhone 4S, iPhone 5, iPhone 5C, and the 2nd, 3d, and 4th generation iPad devices. The 3.3 stable version of Flutter and all following stable releases no longer support 32-bit iOS devices and iOS versions 9 and 10. This means that apps built against Flutter 3.3 and later won’t run on those devices.

Sunsetting macOS 10.11 and 10.12

In the Q4 2022 stable release, we expect to drop support for macOS versions 10.11 and 10.12. This means that apps built against stable Flutter SDKs after that point will no longer work on these versions, and the minimum macOS version supported by Flutter will increase to 10.13 High Sierra.

Bitcode deprecation

Bitcode will no longer be accepted for iOS app submission in the upcoming Xcode 14 release, and projects with bitcode enabled will emit a build warning in this version of Xcode. In light of this, Flutter will drop support for bitcode in a future stable release.

By default, Flutter apps don’t have bitcode enabled, and we don’t expect this to impact many developers. However, if you have enabled bitcode manually in your Xcode project, disable it as soon as you upgrade to Xcode 14. You can do so by opening ios/Runner.xcworkspace and setting the build setting Enable Bitcode to No. Add-to-app developers should disable it in the host Xcode project.

See Apple’s documentation to learn more about bitcode distribution.

Flutter 3.7

Supported platforms

As of the current release, Flutter supports the following platforms as part of Google-tested and best-effort platform tier:

Platform	Version	Channels

Flutter 错误：找不到名为 frontend_server.dart.snapshot 的命令

Caught error: Unsupported operation: Platform._operatingSystem

Flutter 代码运行在 Chrome 上的时候报错 “Caught error: Unsupported operation: Platform._operatingSystem”。

报错的原因是因为代码中使用了 Platform.isIOS、Platform.isAndroid 等函数判断系统类型，可惜的是，这些函数并不能在 Chrome 上运行。

修改方法就是自己封装一个自定义工具类，先使用 kIsWeb 排除一下浏览器。参考如下：

import 'dart:io';

import 'package:flutter/foundation.dart';

class PlatformKit {
  /// 是否是移动设备，如果系统是 Android 、iOS 则返回 true 否则返回 false
  static bool isMobile() {
    return (!kIsWeb) && (Platform.isAndroid || Platform.isIOS);
  }

  /// 是否是macOS，如果系统 macOS 则返回 true 否则返回 false
  static bool isMacOS() {
    return (!kIsWeb) && Platform.isMacOS;
  }
}

import 'dart:io';

import 'package:flutter/foundation.dart';

class PlatformKit {

/// 是否是移动设备，如果系统是 Android 、iOS 则返回 true 否则返回 false

static bool isMobile() {

return (!kIsWeb) && (Platform.isAndroid || Platform.isIOS);

}

/// 是否是macOS，如果系统 macOS 则返回 true 否则返回 false

static bool isMacOS() {

return (!kIsWeb) && Platform.isMacOS;

}

Flutter Web 警告 Local variable for "serviceWorkerVersion" is deprecated

升级到 Flutter 3.22.0 之后，在 Chrome 上运行 Flutter Web 应用程序时收到以下警告：

Launching lib/main.dart on Chrome in debug mode...
Waiting for connection from debug service on Chrome...
Warning: In index.html:40: Local variable for "serviceWorkerVersion" is deprecated. Use "{{flutter_service_worker_version}}" template token instead. See https://docs.flutter.dev/platform-integration/web/initialization for more details.

Launching lib/main.dart on Chrome in debug mode...

Waiting for connection from debug service on Chrome...

Warning: In index.html:40: Local variable for "serviceWorkerVersion" is deprecated. Use "{{flutter_service_worker_version}}" template token instead. See https://docs.flutter.dev/platform-integration/web/initialization for more details.

这个警告的原因是，新版本的 Flutter Web 应用加载 service_worker.js 的方式发生了变化，原来的加载脚本被 {{flutter_bootstrap_js}} 替代。

调整为新的初始化代码即可解决此问题。

原始的代码如下：
