android - Flutter how to solve AndroidX incompatibility

问题描述

When I install the geolocator package in my Flutter project, I get the error in the first picture. When I set the minSdkVerison value to 21, the error changes and I get the 2nd error. But I guess the 2nd error has nothing to do with the geolocator because if I uninstall the geolocator package, I get that error when the minSdkVersion is 21. I tried flutter clean and set multiDexEnabled to true but it didn't fix. How can I solve this problem?

if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'

解决方案

您在 Firestore 中使用什么版本？将 SDK 设置为 21 并保持 multidex 不变，版本 21 处理它。根据您的无效安全状态使用最新版本的地理定位器和 Firestore。
