对flutter有兴趣的小伙伴可以一起学习呀～

好用的命令行

flutter pub pub cache repair ：清理缓存

错误一：

flutter project插入图片异常

xjdMacBook-Pro:flutter_app_layout xj.d$ flutter run -d all
Running "flutter packages get" in flutter_app_layout...          
Error on line 40, column 2 of pubspec.yaml: Expected a key while parsing a block mapping.
 assets:
 ^                                                                                                                                          
pub get failed (65)

flutter插入图片

1.根项目创建文件名为【图像】文件夹

2.将文件复制到文件夹下面

3.pubspec.yaml文件下面配置该图片

注意图的名字都正确，配置和使用都保持一致（楼主该图随便百度下的），否则无法找到资源

错误二：

flutter - >在android stuido错误中打开android模块

Open File

解决办法：

因为是GitHub的上拉下来的代码，gradle4.1，查看自己配置环境的gradle这个版本，是否一致，需改版本。
我解决办法直接删了项目gralde，粘贴自己没有问题的flutter gralde文件，上图。就是这么暴力~~
解决方法一：

解决方法二：

错误三：

异常：Android dependency ‘com.android.support:support-core-utils’ has different version for the compile (25.3.0) and runtime (27.1.1) classpath. You should manually set the same version via DependencyResolution
原因：创建一个lib【common】，app：依赖【common】出现该原因。
解决办法：

subprojects {
//    project.evaluationDependsOn(':app')
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"
            }
        }
    }
}

错误:

日志： Caused by: java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

修改：
MainActivity主题配置：

<activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/Theme.AppCompat"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if
                 there is no splash screen (such as the default splash screen
                 defined in @style/LaunchTheme). -->
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

错误

日志：androidstudio 切换到flutter项目Android报错
Flutter SDK not found. Define location with flutter.sdk in the local.properties file.

解决办法：删android/local.properties文件，运行【flutter build apk】
然后重新打开studio到Android channel，如下图，ok～在这里插入图片描述

错误

混合开发，Native+Flutter
错误提示：

/Users/xx/xx/flutter-project/my_flutter/.android/include_flutter.groovy (/Users/xx/alibaba/flutter-project/my_flutter/.android/include_flutter.groovy)

在这里插入图片描述
修改：补全路径

提示

Androidstudio打开flutter project 无法切换Android版本：【Open Android module in Android Studio】无法选择
正常情况如图：
在这里插入图片描述
解决办法：查看是否有这个.iml文件没有就加进去

错误提示：

编译ios出错：

diff: /Podfile.lock: No such file or directory
diff: /Manifest.lock: No such file or directory
error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

解决方案：
控制台敲命令行：

flutter build ios --release

关闭xcode重启项目

错误

最近在弄IOS打包，遇到的问题是，debug包都没问题，release包安装在手机上面后，页面一直停留在欢迎页面，无法进入首页。
原因：flutter一部分dart包过时，无法支持release
解决：对应更新一下flutter 项目里面依赖都dart包就好了
具体因为哪一个导致的没有细查，大部分都更新了一下，就好了～
