1. mac 無法打開“idevice_id”。
解決辦法:系統偏好設置-安全性與隱私-信任。
2. Could not find an option named "androidx"
AS 創建Flutter項目報上面錯誤信息,可能因爲flutter sdk 版本過低。

3. Mac環境下Android Studio 無法連接iOS模擬器
在mac環境下用Android Studio 寫Flutter,可以啓動iOS 模擬器,但是在設備列表裏找不到模擬器時
打開終端並輸入下面命令:
sudo xcode-select --switch/Applications/Xcode.app/Contents/Developer
之後回車,輸入本機密碼,就可以了
4. Your app isn’t using AndroidX
android gradle.properties下添加
android.enableJetifier=true
android.useAndroidX=true
5. bottom overflowed by 94 pixels
Scaffold下添加如下配置:resizeToAvoidBottomInset: false
原因:防止軟鍵盤彈出時遮擋頁面的東西。當設置爲 true 的時候,軟鍵盤彈出頁面會自動調整尺寸避免遮擋; 當爲 false 的時候則軟鍵盤彈出不會自動調整尺寸。該屬性值默認爲 true。
6. 啓動黑屏
Flutter項目啓動過程:
1、顯示android啓動項activity
2、flutter啓動項activity
3、進入flutter項目的第一個頁面
黑屏對應的是flutter啓動項activity
解決方案:
AndroidManifest.xml中目標activity下加入
<application
android:name="io.flutter.app.FlutterApplication"
android:label="swift_rabbit"
android:icon="@mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<!--Flutter 閃屏頁-->
<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="@drawable/launch_background" />
<!--閃屏頁結束後的Theme-->
<meta-data
android:name="io.flutter.embedding.android.NormalTheme"
android:resource="@style/NormalTheme" />
</activity>
<!-- Don't delete the meta-data below.
This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
<meta-data
android:name="flutterEmbedding"
android:value="2" />
</application>
style.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
<!-- Show a splash screen on the activity. Automatically removed when
Flutter draws its first frame -->
<item name="android:windowBackground">@drawable/launch_background</item>
</style>
<style name="NormalTheme" parent="@android:style/Theme.Black.NoTitleBar">
<item name="android:windowBackground">@drawable/normal_background</item>
</style>
</resources>
normal_background.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/white" />
<!-- You can insert your own image assets here -->
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/naruto" />
</item>
</layer-list>
7. Flutter: Exception in thread “main” java.util.zip.ZipException:
