[英]Flutter (Barcode_scan) build\barcode_scan\extracted-protos\main' specified for property '$4' does not exist
我正在使用这个package 来扫描二维码。 但我升级到 3.x 版本,有错误:
[ +2 ms] FAILURE: Build failed with an exception.
[ +2 ms] * What went wrong:
[ ] Some problems were found with the configuration of task ':barcode_scan:generateDebugProto'.
[ ] > Directory '<projectName>\build\barcode_scan\extracted-protos\main' specified for property '$4' does not exist.
[ +19 ms] * Try:
[ +17 ms] Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
我尝试将main
文件夹添加到extracted-protos
,但是当我运行应用程序时,这个文件夹丢失了。
在花了 2 天时间试图修复它之后。 最后我想出了如何:
Go 到android
文件夹 > build.gradle
文件。 添加行后:
buildscript {
ext.kotlin_version = '1.3.61'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.12' //add this line
}
}
它工作。
