Question

当我尝试启动我的应用程序时突然遇到此错误

Running Gradle task 'assembleDebug'...
/C:/Users/Asus/AppData/Local/Pub/Cache/hosted/pub.dev/flutter_typeahead-3.2.7/lib/src/flutter_typeahead.dart:1248:57: Error: The getter 'errorColor' isn't defined for the class 'ThemeData'.
 - 'ThemeData' is from 'package:flutter/src/material/theme_data.dart' ('/E:/Compressed/flutter_windows_3.24.3-stable/flutter/packages/flutter/lib/src/material/theme_data.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'errorColor'.
              style: TextStyle(color: Theme.of(context).errorColor),
                                                        ^^^^^^^^^^

The Flutter CLI developer tool uses Google Analytics to report usage and diagnostic
data along with package dependencies, and crash reporting to send basic crash
reports. This data is used to help improve the Dart platform, Flutter framework,
and related tools.

Telemetry is not sent on the very first run. To disable reporting of telemetry,
run this terminal command:

    flutter --disable-analytics

If you opt out of telemetry, an opt-out event will be sent, and then no further
information will be sent. This data is collected in accordance with the Google

我曾经删除了dist文件夹的内容，该文件夹位于C:\Users{YourUserName}.gradle\wrapper\dists，但我仍然收到错误。

确实

errorColor

不是有效的 getter。

主题错误颜色可以通过这种方式检索：

Theme.of(context).colorScheme.error

您正在使用

flutter_typeahead

软件包，目前可以升级到 v5.2.0。

升级您的

pubspec.yaml

软件包版本，您可以通过运行以下命令自动检索最新的主要软件包：

flutter pub upgrade --major-versions

这将使用最新的兼容版本的软件包更新您的

pubspec.yaml

文件。验证

flutter_typeahead

是否已正确升级。
