具有无限高度的 Flutter ListView 异常

我正在 Android Studio 上开发一个新的 Flutter 应用程序。我的应用程序的一页从Future. 有了未来的结果,我正在创建一个ListView.builder()

这是代码:

Widget encabezados(BuildContext context, AsyncSnapshot snapshot)
  {
    ListView(
      children: <Widget>[
        new Card(
          elevation: 3,
          child: Row(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              SizedBox(width: 0.0,),
              Category(
                backgroundColor: Colors.deepOrange,
                val: clientesacobrar.toString(),
                title: "Clientes a cobrar",
              ),
              SizedBox(width: 10.0,),
              Category(
                backgroundColor: Colors.blue,
                title: "Clientes cobrados",
                val: clientescobrados.toString(),

                val: formatter.format(montoacobrar),
                //val: records.length.toString(),
                backgroundColor: Colors.green,
                title: "Monto a cobrar",
              )
            ],
          ),

        new ListView(
          shrinkWrap: true,

Flutter Firebase 远程配置类中没有虚拟方法 isDeveloperModeEnabled()Z .../FirebaseRemoteConfigSettings

我最近升级了 Flutter 项目中的所有 firebase 库。之后,我收到消息:

/flutter (27126): [ERROR:flutter/shell/platform/android/platform_view_android_jni_impl.cc(43)] java.lang.NoSuchMethodError: Lcom/google/firebase/remoteconfig/FirebaseRemoteConfigSettings 类中没有虚拟方法 isDeveloperModeEnabled()Z;或其超类('com.google.firebase.remoteconfig.FirebaseRemoteConfigSettings' 的声明出现在 /data/app/package_name-1UBO7FEPHLsC2_eb7itJLA==/base.apk!classes3.dex 中)

之后,我的应用程序因错误而崩溃:

[致命:flutter/shell/platform/android/platform_view_android_jni_impl.cc(942)] 检查失败:CheckException(env)。

目前我正在使用:

firebase_remote_config: ^0.4.0+2

firebase_core:0.5.0+1

我在 android/build.gradle 中的依赖项:

dependencies {
    classpath 'com.android.tools.build:gradle:3.6.4'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.4'
