이런 에러가 뜰때, 

flutter sdk, java sdk, kotlin sdk, Gradle, Android Plugin 버전을 체크할게 아니고. 

Dex 단어를 힌트로 보고 

 

 

 

 

 

build.gradle쪽에 

buildTypes {
    release {  
    	...
        multiDexEnabled true
        minifyEnabled true
        shrinkResources true
        ...
    }

    debug {
		...
        multiDexEnabled true
        minifyEnabled true
        shrinkResources true
        ...
    }
}

이런식으로 multiDexEnabled와 minifyEnabled, shrinkResources를 true로 주면 됩니다.
