flutter 報錯解決 解決方案 ：java
找到你的flutter安裝目錄，好比個人是~/Library/flutterandroid
進入~/Library/flutter/packages/flutter_tools/gradleapache
修改flutter.gradle， 在buildscript裏的repositories的google()下面加上mavenCentral()， 再運行便可。以下所示api
buildscript {
repositories {
google()
mavenCentral() // add this line
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
}
報錯信息以下：app
