Answer 1

The topic is related to " The Complete Flutter Development Bootcamp Using Dart "

When something wrong and doesn't work,
It's okay in the software development world.

I also had the same issue on Android after cloning and trying to launch them

• https://github.com/londonappbrewery/destini-challenge-starting
• https://github.com/londonappbrewery/bmi-calculator-flutter

So, here are steps to get rid of the problem

1) your-cool-flutter-project/android/app/build.gradle

In this file be sure that you have 29 API used two times if you see 27 then modify to 29 like these

  compileSdkVersion 29
  targetSdkVersion 29

2) your-cool-flutter-project/android/gradle.properties

Check that file has these two lines if they miss then add them

android.useAndroidX=true
android.enableJetifier=true

That's all. Take a breath. Relax. And launch the app =)

• I very hope you have the latest Android and Flutter installed ;)*

Answer 2

I am a newbie to android studio and flutter development. I was trying out the same dicee flutter app by cloning it on my machine. I don't know exactly what the problem was, but in my android/gradle/build.gradle file of the cloned project I edited the following line

classpath 'com.android.tools.build:gradle:3.5.3'

to

classpath 'com.android.tools.build:gradle:3.5.0'

which was similar to the projects created by me offline. This might be due to running an older version of this gradle stuff on my machine. I am not sure but it worked for me for the time being.

Answer 3

在我不知道为什么会发生之前，我遇到了这个问题，但我所做的是关闭项目并再次打开它，这似乎解决了我的问题。

Answer 4

Or just clone fixed repos =)
