Android specific options (useWideViewPort, loadWithOverviewMode, supportZoom, builtInZoomContros, displayZoomControls) not working on apk release

[furiousdazzewizard]

Environment

Flutter version: v1.12.13+hotfix.7, on Microsoft Windows [Version 10.0.17763.973] Plugin version: Flutter plugin version 43.0.1 on Android Studio 3.5 Android version: Android 9 (API 28) iOS version: N/A Xcode version: N/A Device information: SM J400M • 42006eb568b2a543 • android-arm • Android 9 (API 28)

Description

The above mentioned android specific options work fine on the debug version of the app. On the release version, however, neither of those options work (seems to be unavailable).

Expected behavior: For example, the web page should be displayed in overview mode, with a desktop-like view.

Current behavior: the web page is displayed in its original size, bigger than the screen size of the webview.. In addition, zoom support is not available so it is not possible to fit size.

Steps to reproduce

1. Make a project with a web view to shop an given url with the above mentioned android options activated: . . . @override Widget build(BuildContext context) { data = ModalRoute.of(context).settings.arguments; return Scaffold( appBar: AppBar( title: Text( 'any text...', style: GoogleFonts.indieFlower(), ), elevation: 15.0, ), body: InAppWebView( initialUrl: data['url'], initialHeaders: {}, initialOptions: InAppWebViewWidgetOptions( crossPlatform: InAppWebViewOptions( preferredContentMode: InAppWebViewUserPreferredContentMode.DESKTOP, ), android: AndroidInAppWebViewOptions( useWideViewPort: true, loadWithOverviewMode: true, supportZoom: true, builtInZoomControls: true, displayZoomControls: true, ), ), onWebViewCreated: (InAppWebViewController controller) { webView = controller; }, ), ); }
2. Generate the debug apk and/or run the app from IDE and you will get the EXPECTED behaviour
3. Generate the release apk, install & run it in the smartphone and you will get the CURRENT behaviour

after a couple of time to cater with this issue, I just get a workaround to solve this,

when building a release build of apk, pass also the --no-shrink to flutter build flutter build apk --no-shrink

I got the following debug lot when enabled the debug log option in WebView, and it is only happened in release build but not debug build.

02-24 16:34:50.051 13671 13671 D Options : No field useShouldOverrideUrlLoading in class Lcom/pichillilorenzo/flutter_inappwebview/InAppWebView/G; (declaration of 'com.pichillilorenzo.flutter_inappwebview.InAppWebView.G' appears in base.apk) 02-24 16:34:50.051 13671 13671 D Options : No field initialScale in class Lcom/pichillilorenzo/flutter_inappwebview/InAppWebView/G; (declaration of 'com.pichillilorenzo.flutter_inappwebview.InAppWebView.G' appears in base.apk)

hope it may help you

I just use AndroidInAppWebViewOptions : databaseEnabled: true, domStorageEnabled: true,

Successfully run in debug mode，but fail in flutter build apk --target-platform android-arm,android-arm64 --split-per-abi
