每次我使用 Android Studio 模拟器在 VS Code 上运行 Flutter 项目时，都会遇到此错误，但我不知道如何修复它。有什么帮助吗？
WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 34
This Android Gradle plugin (7.3.0) was tested up to compileSdk = 33
This warning can be suppressed by adding
android.suppressUnsupportedCompileSdk=34
to this project's gradle.properties
The build will continue, but you are strongly encouraged to update your project to
use a newer Android Gradle Plugin that has been tested with compileSdk = 34

Setting the namespace via a source AndroidManifest.xml's package attribute is deprecated.
Please instead set the namespace (or testNamespace) in the module's build.gradle file, as described here: https://developer.android.com/studio/build/configure-app-module#set-namespace
This migration can be done automatically using the AGP Upgrade Assistant, please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.

我尝试删除gradle并重新安装，仍然没有帮助，所以这不是gradle的问题。 我也尝试更新我的 kotlin 版本，但仍然没有帮助。
我刚刚创建了一个新项目，这是我在输出中收到的一条消息：
[first_app] flutter pub get --no-example
Resolving dependencies...
Because first_app depends on cwc_flutter any which doesn't exist (could not find package cwc_flutter at https://pub.dev), version solving failed.
exit code 69
这也是 main.dart 文件：
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatelessWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
Widget build(context) {
return Text(title);
}
}
这是 pubspec.yaml

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter

# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg

# An image asset can refer to one or more resolution-specific "variants", see

# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:

# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
#
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
好吧， 正如错误已经提到的：
Because first_app depends on cwc_flutter any which doesn't exist (could not find package cwc_flutter at https://pub.dev), version solving failed. exit code 69没有名为
cwc_flutter1. Remove `cwc_flutter` from your pubspec.yaml
2. Run flutter clean in your terminal
3. When Finished now run flutter pub get
然后等待完成后，运行您的应用程序！
如果您修复了错误，请告诉我...
编码快乐:)
更多信息：错误 69 是指无法获取包
文件，如果它已经失败，你必须修复 你的puzspec.yaml问题。您应该从您的pubspec.yaml文件中删除cwc_flutter包pubspec.yaml
