Mapbox SDK Registry Token 为空

Question

我在我的 flutter 应用程序上安装 mapbox_gl 插件时遇到问题...

我确实遵循了那里的官方说明：

https://pub.dev/packages/mapbox_gl

但是每当我点击 flutter 运行时，我都会收到相同的消息：

SDK Registry token is null. See README.md for more information.

这导致：

Could not get unknown property 'android' for project ':mapbox_gl' of type org.gradle.api.Project.

看起来像一个 gradle 问题...我错过了什么？

我正在使用 beta flutter 频道和运行 --no-sound-null-safety

这是我的代码：

    ext.kotlin_version = '1.3.50'

                // Do not change the username below.
                // This should always be `mapbox` (not your username). 
                username = 'mapbox'
                // Use the secret token you stored in gradle.properties as the password
                password = "[Yes I checked this token multiple times]"
            }
        }
    }
}

我在安装这个插件时也遇到了问题最后，我设法导入运行 mapbox_gl: ^0.10.0 只需按照以下步骤操作：

在你的android/app/build.gradle设置

compileSdkVersion 29

minSdkVersion 20

targetSdkVersion 29

在android/build.gradle设置

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

在android/gradle/wrapper/gradle_wrapper.properties中设置

distributionUrl=https://services.gradle.org/distributions/gradle-5.6.2-all.zip

终于在你的pubspec.yaml导入

mapbox_gl: ^0.10.0

Answer 2

我遇到了同样的问题，然后这样解决：

删除 mapbox_gl 包并在 pubspec.yaml

flutter_map

在位于 <project root>/android/app/src/main/AndroidManiFest.xml

<uses-permission android:name="android.permission.INTERNET"/>

现在我们可以使用 FlutterMap() 小部件，但您需要在 mapbox 上创建一个帐户并复制“默认 public 令牌”
然后在“工具和资源”部分单击“在 Mapbox Studio 中设计”，如 here，然后在打开的新页面单击“新样式”
在这里你可以选择任何你想要的风格this
首先点击“分享您的风格”图标（参见 here) and go to "Third party" tab and chose "CARTO" then copy the "Integration URL" like here
现在我们需要转到“Tilesets”page and copy the ID of Tilesets like here
让我们使用FlutterMap()

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong2/latlong.dart' as latLng;

class MapScreen extends StatefulWidget {

  @override
  _MapScreenState createState() => _MapScreenState();
}

class _MapScreenState extends State<MapScreen> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Chose From Map'),
      ),
      body: FlutterMap(
        options: MapOptions(
          center: latLng.LatLng(51.5, -0.09),
          zoom: 13.0,
        ),
        layers: [
          TileLayerOptions(
            urlTemplate: 'use Integration URL here',
            additionalOptions: {'accessToken': 'use Default public token here',
              'id': 'use the ID of Tilesets here',
            },
          ),
        ],
      ),
    );
  }
}

现在运行你的应用程序。

将此行添加到您的 gradle.properties 文件中：

MAPBOX_DOWNLOADS_TOKEN=YOUR MAPBOX DOWNLOADS ACCESS TOKEN

按照此文档创建您的令牌： https://docs.mapbox.com/android/maps/guides/install/
