一：

在命令行運(yùn)行恼布，后會生成upload-keystore-anyou.jks文件竭沫，這個(gè)文件名自己定義：
keytool -genkey -v -keystore E:/jks/uploadcar01.jks -keyalg RSA -keysize 2048 -validity 10000 -alias uploadcar01

密鑰自己準(zhǔn)備一個(gè)：mycarab

將.jks文件拷貝到android跟目錄下咪辱， jks文件名和 上面的-alias后面的名字一致。

二：在文件 android/local.properties中添加：

storePassword=mycarab
keyPassword=mycarab
keyAlias=uploadcar01
storeFile=../uploadcar01.jks

三：在 android/app/build.gradle文件里面的 android節(jié)點(diǎn)里面添加：

signingConfigs {
        release {
            keyAlias localProperties['keyAlias']
            keyPassword localProperties['keyPassword']
            storeFile localProperties['storeFile'] ? file(localProperties['storeFile']) : null
            storePassword localProperties['storePassword']
        }
        debug {
            keyAlias localProperties['keyAlias']
            keyPassword localProperties['keyPassword']
            storeFile localProperties['storeFile'] ? file(localProperties['storeFile']) : null
            storePassword localProperties['storePassword']
        }
   }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.release
        }
        debug {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }

四： flutter run --release

大功告成，可以在命令行打包apk了
flutter build apk --release --no-sound-null-safety

權(quán)限配置：

android/app/src/main/AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

圖標(biāo)更改：

android/app/src/main/AndroidManifest.xml

   <application
        android:label="車測試"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_car"> 

keytool -list -v -keystore uploadcar01.jks
查看jks文件內(nèi)容

添加啟動圖片：

android\app\src\main\res\drawable\launch_background.xml
中添加：

 <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/welcome" />
   </item>
