App fails to run when I add better_player fllutter package to my dependencies in pubspec.yaml

Time：12-30

Describe the bug

Cannot run any flutter project on Android Emulator or iPhone Simulator once better_player is added to dependencies (even if it is not used)

To Reproduce

Steps to reproduce the behavior:

  1. In Flutter 2.8.0., I ran flutter create new_2_8_0 for a new basic project. (the problem is the same with 2.8.1)
  2. Running this project on my Pixel 2 AP31 (android-x64) emulator works fine, albeit with some warning messages:

  1. Then, I ran flutter pub add better_player in the directory of the project.
  2. Trying to run the project again yields many errors (full log in this Pastebin link as it is too long: https://pastebin.com/aTazjdi1):

CodePudding user response：

for the Android error, it tells you that you need to enable multiDex in your project, here is how

in android/app/build.gradle add this line multiDexEnabled = true in the defaultConfig

your defaultConfig should look something like this

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.test.test"
    minSdkVersion 21
    targetSdkVersion 30
    multiDexEnabled = true
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

regarding the iOS error it says

dependency were found, but they required a higher minimum deployment target.

so increase the minimum deployment target. you can find it in ios/flutter/AppFrameworkInfo.plist named MinimumOSVersion and looking like this

<key>MinimumOSVersion</key> 
<string>9.0</string>
