Flutter Error: MediaQuery.of() called with a context that does not contain a MediaQuery
You need a MaterialApp or a WidgetsApp arround your widget. They provide the MediaQuery.
* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: <...>
The number of method references in a .dex file cannot exceed 64K.
Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html
Add multidex library to android app depedency (/android/app/build.gradle):
android {
...
defaultConfig {
...
multiDexEnabled true
}
...
}
...
dependencies {
implementation 'com.android.support:multidex:1.0.3' // use latest version
...
}
*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
