我的Flutter应用程序显示错误时，我试图在安卓手机或模拟器运行

Question

这是错误

当我试图在模拟器中启动时，每个颤振项目都会显示这种错误，但它会在chrome中运行。我试图改变不同的依赖关系，但不工作，它只显示这个错误一次又一次

Launching libmain.dart on RMX3511 in debug mode...

这是我的构建。级文件

buildscript {
ext.kotlin_version = '1.6.10'
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:7.1.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Try replace all:

repositories {
google()
mavenCentral()
}

:

repositories {
mavenCentral()
google()
}
