刚刚使用 flutter create 'name' 创建的 Flutter 新项目出错

Question

我只是使用 flutter create 在 flutter 中创建了一个新项目，但是当我想运行该项目时出现错误。

'我已经重新安装了可视化代码，android studio，我用所有下载创建了模拟器，但什么也没有...... 这是代码。'

 allprojects {
    repositories {
         google()
         mavenCentral()
  }
}

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

 tasks.register("clean", Delete) {
      delete rootProject.buildDir
 }

我有这个错误

Build file 'C:\Users\Dan\Flutter Projects\casa1\android\build.gradle' line: 13'

What went wrong:
A problem occurred evaluating root project 'android'.
> Build completed with 1 failures.
> org/bouncycastle/jce/provider/BouncyCastleProvider

Answer 1

确保您在 build.gradle 文件中声明了必要的依赖项。

  dependencies {
     implementation 'org.bouncycastle:bouncycastle:1.68'
  }
