[英]Where is the value of "flutter.minSdkVersion" in Flutter project initialized?
I have created a new Flutter project, and this is how the minSdkVersion looks like in the app/build.gradle
file:我创建了一个新的 Flutter 项目,这就是 minSdkVersion 在
app/build.gradle
文件中的样子:
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Where is the value of flutter.minSdkVersion
set? flutter.minSdkVersion
的值在哪里设置?
Note that previously, that config value looked like the following:请注意,以前,该配置值如下所示:
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion 19 //*** This is the part that needs to be changed, previously was 16
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
Also, this is the content of the android/local.properties
file:此外,这是
android/local.properties
文件的内容:
sdk.dir=/Users/usernaem/Library/Android/sdk
flutter.sdk=/Users/username/flutter
flutter.buildMode=release
flutter.versionName=1.0.0
flutter.versionCode=1
As you can see, the value of flutter.minSdkVersion
is not set there, but the project can be compiled and built successfully.可以看到,这里并没有设置
flutter.minSdkVersion
的值,但是工程可以编译构建成功。
Where are the flutter.minSdkVersion
and flutter.targetSdkVersion
variables initialized? flutter.minSdkVersion
和flutter.targetSdkVersion
变量在哪里初始化?

Go to this file in your flutter extracted folder: Go 到您的 flutter 提取文件夹中的此文件:
flutter/packages/flutter_tools/gradle/flutter.gradle颤振/包/flutter_tools/gradle/flutter.gradle
There you can find all static variables.在那里您可以找到所有 static 变量。
You should change from local.properties following instruction:您应该按照以下说明从 local.properties 进行更改:
First go to the android-> local.properties
首先 go 到 android->
local.properties
And changes from here local.properties
并从这里更改
local.properties
add this line添加这一行
flutter.minSdkVersion=19
flutter.targetSdkVersion=28
flutter.compileSdkVersion=28
NB: you don't find the local.properties
you create yourself注意:您找不到自己创建的
local.properties
Put in your android/local.propertie
file the variable:将变量放入您的
android/local.propertie
文件中:
Example:例子:
flutter.minSdkVersion=21
And change in android/app/build.gradle
并更改
android/app/build.gradle
localProperties.getProperties('flutter.minSdkVersion') // flutter.minSdkVersion
Just replace flutter.minSdkVersion
with your required value such as 19
like old style只需将
flutter.minSdkVersion
替换为您需要的值,例如旧样式的19
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion 19
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Follow the path /android/app/build.gradle按照路径/android/app/build.gradle
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.sample.com"
// You can update the following values to match your application needs.
// For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
minSdkVersion 23
targetSdkVersion 33
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
