Flutter兼容性问题：Could not get unknown property ‘flutter‘ for extension ‘android‘

项目背景

部们有两个项目，一个原生项目，一个Flutter项目，现在要把Flutter项目融入进来，于是技术选型是采用原生+Flutter混编方式，因为Flutter项目用了第三方插件gal，于是引入进来以后报错了：

bash 复制代码

Build file 'C:\Users\ws\AppData\Local\Pub\Cache\hosted\pub.dev\gal-2.3.2\android\build.gradle' line: 18

A problem occurred evaluating project ':gal'.
> Could not get unknown property 'flutter' for extension 'android' of type com.android.build.gradle.LibraryExtension.

解决方案

在宿主工程根目录下的build.gradle文件（不是.android/build.gradle文件）加入如下代码：

groovy 复制代码

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:8.12.0'
    }
}

plugins {
    id 'com.android.application' version '8.10.0' apply false
    id 'com.android.library' version '8.10.0' apply false
    id 'org.jetbrains.kotlin.android' version '2.1.0' apply false
    id "org.jetbrains.kotlin.kapt" version "2.1.0" apply false
    id "com.google.gms.google-services" version '4.3.15' apply false
    id "com.google.firebase.crashlytics" version '2.9.5' apply false
    id "com.google.firebase.firebase-perf" version "1.4.2" apply false
    id "io.github.JailedBird.ARouterPlugin" version('1.0.2') apply false
    id "com.huawei.agconnect" version('1.9.1.301') apply false
    //    id "com.alibaba" version('1.0.2') apply false
//    id "com.sensorsdata.analytics.android" version '3.5.2' apply false
}

// 解决gal插件报错：
// A problem occurred evaluating project ':gal'.
//> Could not get unknown property 'flutter' for extension 'android' of type com.android.build.gradle.LibraryExtension.
ext.flutter = [
        compileSdkVersion: 35,
        minSdkVersion    : 24,
        targetSdkVersion : 35,
        ndkVersion       : "27.0.12077973"
]

apply from: 'config.gradle'

subprojects {
	...
}
