How can I update dart version in existing flutter project?
问题
以下是翻译好的部分：
当我想要将“flutter_iconpicker”包添加到我的当前Flutter项目中时，它会出现下面的错误。我已经更新了我的计算机上的Flutter和Dart版本，但没有成功。
当前Dart SDK版本为2.18.1。
因为sample_project依赖于flutter_iconpicker >=3.2.3，它要求SDK版本 >=3.0.0 <4.0.0，版本解决失败。
pub get失败（1；因为sample_project依赖于flutter_iconpicker >=3.2.3，它要求SDK版本 >=3.0.0 <4.0.0，版本解决失败。）
flutter --version输出：

When I want to add the "flutter_iconpicker" package to my current flutter project, it gives the error in question below. I updated the flutter and dart versions on my computer but that didn't work.
The current Dart SDK version is 2.18.1.
Because sample_project depends on flutter_iconpicker >=3.2.3 which requires SDK version >=3.0.0 <4.0.0, version solving failed.

我在Android Studio中遇到了问题。我注意到，当我尝试在Vs Code或终端中运行它时，我没有收到错误。后来我注意到我的Dart SDK路径 "Android Studio > 设置 > 语言 > Dart > Dart SDK路径" 与旧版本相关联。我通过在这里更改路径为当前的SDK路径来解决了我的问题。
感谢所有回复的人。
英文:
I was getting the issue in Android Studio. I noticed that when I try to run it with Vs Code or via terminal, I don't get an error. Later I noticed that my dart sdk path "Android Studio>Settinigs>Languages>Dart>Dart Sdk Path" was linked to an old version. I solved my problem by changing the path here with the current sdk path.
