There is any method for webview cache Optimization in flutter? - flutter

Question

I use flutter_inappwebview for fetching the website into the flutter app. I want to save all the resources like JS and CSS file content into the cache from website during webview start and then when I call same website the resources will intercept and inject the cached files into the webview. Is this possible.. If possible then how.. please explain with example. Thank you.

Answer 1

note: caching is already enabled for this plugin by default. but what you're asking is offline-mode which flutter_inappwebview plugin does not support yet.
the cache you're refering to is not the cache that browsers use (mobile or desktop) what you're refering to is basically called offline-mode in the world of browsers.
in regard to the flutter_inappwebview plugin there is already an issue (or two) about this feature you're looking for. and i believe it is not implemented yet.
you should keep an eye on these github issues issue-561 & issue-366

That flutter_inappwebview package has already a property, cacheEnabled with default parameter, true. You don't need to do anything about this. If you don't want to store cache files, then you can set it to false.
///Sets whether WebView should use browser caching. The default value is `true`.
///
///**NOTE**: available on iOS 9.0+.
bool cacheEnabled;
And, the clearCache property with the default value, 'false'.
///Set to `true` to have all the browser's cache cleared before the new WebView is opened. The default value is `false`.
bool clearCache;
