使用 Firestore 获取数据时出现 Flutter 错误

Question

This is the error that I am getting in debug console:

FAILURE: Build failed with an exception.

* Where:
Script 'C:\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 358

* What went wrong:
A problem occurred configuring project ':cloud_firestore_web'.
> Could not find method implementation() for arguments [project ':firebase_core'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s
Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

Also yes I have applied google dependencies.

Checked flutter doctor and no issues found.

packages:

import 'package:flutter/material.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

Initialized:

FirebaseFirestore firestore = FirebaseFirestore.instance;
CollectionReference popular = FirebaseFirestore.instance.collection('popular');

main code:

StreamBuilder( stream: popular.snapshots(), builder: (BuildContext context, AsyncSnapshot snapshot) { if (snapshot.hasError) { 
  return Text('Something went wrong'); }

  if (snapshot.connectionState ==
  ConnectionState.waiting) {
  return Text("Loading");
  }

  return new ListView(
    children: snapshot.data.documents
    .map((DocumentSnapshot document) {
      return new ListTile(
       leading: Image.network(document.data()['image']),
      );
    }).toList(),
  );
}),

The stacktrace:

\android>./gradlew build --stacktrace
