当项目已经评估时不能运行 Project.afterEvaluate(关闭)

Question

目前我遇到这个错误：

Microsoft Windows [Version 10.0.19043.1526]

C:\Users\Flutter\StudioProjects\nomadnet>flutter run
Using hardware rendering with device sdk gphone x86 arm. If you notice graphics artifacts, consider enabling software rendering with
"--enable-software-rendering".
Launching lib\main.dart on sdk gphone x86 arm in debug mode...

FAILURE: Build failed with an exception.

* Where:
Script 'C:\Users\Flutter\flutter_windows_2.10.1-stable\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 421

A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > Cannot run Project.afterEvaluate(Closure) when the project is already evaluated.

我已经试过这个东西了：

我也尝试了更多的东西，但我不再了解它们了

我的代码：

app/build.gradle:

    repositories {

        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

    repositories {

        jcenter()
    }

allprojects {
    repositories {

        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我有最新的flutter版本，还有最新的flutter插件版本

PS：我使用 oneSignal。

请帮帮我！

Answer 1

这似乎是 OneSignal Grandle 插件的一个已知问题。

Github OneSignal Issue

在讨论中提出了一些解决方案，它们似乎破坏了 OneSignal 或引起更多问题。

其中两个是：

在“android/app/build.gradle”的序列中将 onesignal 插件放在它后面。 信用：Direnalex comment
降级 Flutter 和 Kotlin。 图片来源：Dgilperez comment

我的建议是提请注意 Github 问题，以便 OneSignal 社区可以解决它。

Answer 2

为了解决上面的以下问题，我想看看你的 flutter doctor，和 verbose once 运行 app.

但请先尝试这个

1. downgrade your pub library , then do a pub repair, and flutter clean.

Did this solved the issue? if not Then do the following below.

2. downgrade your flutter version, and choose the stable channel for the down graded version, do a flutter clean, then pub repair, and fix the codes of yours to match the down graded version.
