我在使用 flutter_google_places 时遇到了问题。自动完成功能不起作用并E/SpannableStringBuilder(32620): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length在控制台中返回。

我有一个注册的 api_key。

这是代码

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter/widgets.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';
import 'package:google_maps_webservice/places.dart';
import 'package:flutter_google_places/flutter_google_places.dart';
import 'package:geocoder/geocoder.dart';

const kGoogleApiKey = "api_key";

GoogleMapsPlaces _places = GoogleMapsPlaces(apiKey: kGoogleApiKey);

class _CreateNewPostFormState extends State<CreateNewPostForm> {
  _getForm(BuildContext context, double screenWidth, double screenHeight) {
    switch (_dropDownValue) {
      case 1:
        {
          return Form(
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: <Widget>[
                Container(
                  width: screenWidth * 0.9,
                  padding: EdgeInsets.symmetric(vertical: 0, horizontal: 16),
                  margin: EdgeInsets.symmetric(vertical: 8),
                  decoration: BoxDecoration(
                    borderRadius: BorderRadius.circular(30),
                    color: Colors.grey[200],
                  ),
                  child: TextFormField(
                    onTap: () async {
                      Prediction p = await PlacesAutocomplete.show(context: context, apiKey: kGoogleApiKey);
                    },
                    keyboardType: TextInputType.text,
                    decoration: InputDecoration(
                      border: InputBorder.none,
                      hintText:
                          AppLocalizations.of(context).translate('event_place'),

我应该怎么做才能有工作代码？

欢迎所有帮助谢谢！
