Flutter:- already_active，图像选择器已经激活，null，null

Question

每次我在发布模式下按选择图像时，它都会向我显示此错误

E/flutter (24004): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(already_active, Image picker is already active, null, null)

在调试模式下它工作正常

Answer 1

将 Gradle 版本降级为：类路径 'com.android.tools.build:gradle:3.5.4'

Answer 2

降级后Gradle版本更改kotlin版本
这是我 ext.kotlin_version = '1.6.10' 'com.android.tools.build:gradle:4.1.0'

的版本

找到你的

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }
