1.2 Mac, Flutter doctor, ✗ Unable to locate Android SDK.

//简单的解决办法:
flutter config --android-sdk $HOME/Library/Android/sdk

1.3 无法Pod安装时

 rm ios/Podfile.lock
 flutter build ios

1.4 Exception：“failed to set registerPlugins”

打开 ios目录下的AppDelegate.swift文件

添加

import flutter_downloader

Bool 回调添加

FlutterDownloaderPlugin.setPluginRegistrantCallback(registerPlugins)

尾部添加

private func registerPlugins(registry: FlutterPluginRegistry) {
    if (!registry.hasPlugin("FlutterDownloaderPlugin")) {
       FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin"))
    }
}

main.dart完整代码

import UIKit
import Flutter
import flutter_downloader

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    FlutterDownloaderPlugin.setPluginRegistrantCallback(registerPlugins)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

private func registerPlugins(registry: FlutterPluginRegistry) {
    if (!registry.hasPlugin("FlutterDownloaderPlugin")) {
       FlutterDownloaderPlugin.register(with: registry.registrar(forPlugin: "FlutterDownloaderPlugin"))
    }
}

1.5 XCode archive error 'No such module flutter_downloader' when using AppDelegate.swift

None of the above solutions worked for me so this is how I solved mine:

  1. Run flutter clean
  2. Open the project folder navigate to ios directory and delete the 'Pods' folder
  3. Run flutter pub get
  4. Open terminal and navigate to ios directory in your project folder and run pod install
  5. When done, open 'Runner.xcworkspace'
  6. In Xcode, clean the build folder by going to Product > Clean Build Folder
  7. Build the project (Product > Build) and everything should work fine.

1.6 Encountered error while building for device.

warning: The iOS deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of
    supported deployment target versions is 9.0 to 14.0.99. (in target 'JPush' from project 'Pods')

  • 先用Xcode编译运行一遍。修改target deployment version

  • Xcode编译出现错误，需要用Xcode清除错后才行。

1.7 “Waiting for another flutter command to ...”

执行 Flutter 包管理相关命令时有可能遇到 Waiting for another flutter command to release the startup lock... 这样的错误，可尝试杀死所有的 dart 进程解决：

// Linux
killall -9 dart

// Windows
taskkill /F /IM dart.exe

// Mac
rm ~/flutter/bin/cache/lockfile

1.8 Command PhaseScriptExecution failed with a nonzero exit code

Xcode报错：“Command PhaseScriptExecution failed with a nonzero exit code”

Android Studio报错：“Could not build the precompiled application for the device .Error launching application on xx.”

可以模拟器跑，无法在真机运行。

rm ~/flutter/bin/cache/lockfile

1.9 Flutter plugin not installed and Dart plugin not installed errors #69514

Plugin folder has changed in 4.1 version; From : ~/Library/Application\ Support/AndroidStudio4.1 To: ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins

Temporary fix as suggested in the above answer;

ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1

1.10 打包apk，谷歌服务连接失败

1、关闭gradle代理

2、修改项目/android/build.gradle

buildscript {
    repositories {
       // google()
        // jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

   }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

allprojects {
    repositories {
        // google()
        // jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

    }
}

3、打开你flutter SDK目下/Users/gaoxiong/flutter/packages/flutter_tools/gradle/flutter.gradle

与第二步一样，编辑buildscript下的repositories属性。

4、打开/android/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.9-rc-1-all.zip
//修改路径为本地路径
distributionUrl=file\:///Users/gaoxiong/gradle/gradle-6.9-rc-1-all.zip

1.11 CocoaPods did not set the base configuration

CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target Runner to Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig or include the Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig in your build configuration (Flutter/Release.xcconfig).

1.12 PluginApplicationException: Failed to apply plugin [id ‘com.android.internal.version-check‘]

#在gradle.properties文件中添加
android.overridePathCheck=true

1.13 Execution failed for task':app:compileDebugKotlin'.

gradle clean build

1.14 修改bundle ID 后，需要同步修改文件夹

1.15 安卓webview_flutter支持缩放

//webView  
void initState() {
    super.initState();
  //重要
    if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();
}

//FlutterWebView.java 
    webView.getSettings().setUseWideViewPort(true);
    webView.getSettings().setSupportZoom(true);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setDisplayZoomControls(true);

1.16 NoSuchMethodError: The getter 'length' was called on null.

json对象没有传递model所有的属性字段。

1.17 No such module 'HandyJSON'

Xcode模拟器报错，真机不报错。

不知道具体原因。

1.18 flutter_localizations from sdk depends on intl 0.17.0 and fstore depends on intl ^0.16.1, flutter_localizations from sdk is forbidden

This is happening because flutter_localizations need intl: ^0.16.1 while the last version needed intl: ^0.17.0-nullsafety.2

By overriding the existing dependency we can resolve this issue

Adding this to pubspec.yaml solved it:

dependency_overrides:
   intl: ^0.17.0-nullsafety.2

1.19 Could not find an option named "devtools-server-address".

 killall java

1.20 Failed to list versions for com.google.android.gms:play-services-location

注释 location 插件

1.21 Floor使用

floor.codes/getting-sta…

通过在我们的项目根目录下运行:

#首次生成
flutter packages pub run build_runner build
#如果需要在文件变动时，自动运行命令使用
flutter packages pub run build_runner watch

更新数据冲突策略

@Update(onConflict: OnConflictStrategy.replace)
@Insert(onConflict: OnConflictStrategy.rollback)

写Entity

import 'package:floor/floor.dart';

@entity
class Task {
  @PrimaryKey(autoGenerate: true)
  final int? id;

  final String message;

  Task(this.id, this.message);

  @override
  bool operator ==(Object other) =>
      identical(this, other) ||
      other is Task &&
          runtimeType == other.runtimeType &&
          id == other.id &&
          message == other.message;

  @override
  int get hashCode => id.hashCode ^ message.hashCode;

  @override
  String toString() {
    return 'Task{id: $id, message: $message}';
  }
}
