Implementing this, directory create error and such.

[iBuaSpaz]

I feel its been quite a hasstle to make this work, but im getting far now.

I created a function in my main.dart file

`Future main() async {
WidgetsFlutterBinding.ensureInitialized();
FlutterMapTileCaching.initialise(await RootDirectory.normalCache);
FMTC.instance;

SystemChrome.setPreferredOrientations(
[
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
],
).then((val) {
runApp(
const MyApp(),
);
});
}`

works fine, then in my map_control.dart file i have my map code (map and so on loads without issues)

children: [ TileLayer( tileProvider: FMTC.instance('cache_maps').getTileProvider(), urlTemplate: 'https://{s}.tile.thunderforest.com/{style}/{z}/{x}/{y}{r}.png?apikey={apiKey}', subdomains: const ['a', 'b', 'c'], additionalOptions: const { 'style': 'atlas', 'apiKey': '<apikey>', }, userAgentPackageName: 'dev.myapp.example', maxZoom: 22, minZoom: 12, ),

In this i have two issues:

E/flutter (14329): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: FileSystemException: Cannot create file, path = '/data/user/0/com.example.myapp/app_flutter/fmtc/stores/cache_maps/tiles/[email protected]_apikey=<apikey>' (OS Error: No such file or directory, errno = 2)

So it seems it dont create a folder to store the tiles in.

second issue is, it saves the apikey as part of the image file name, im not really interested in this, is it possible to remove that? (it would not be required to have the api key i guess, to load the cache image), everything after ? should be removed and not checked on store/get the cache tile.

Any help with these two issues is appricated.

Hi @iBuaSpaz,

Please migrate to v7, that should help solve the issues.
In terms of the query parameter (everything after '?' in the URL), in v7 it is more hidden inside the database, but can still be read. Unfortunatley, this is necessary to keep - some tile servers have the coordinates there, which make the URL unique. This uniqueness is how the algorithm locates the cached tile, it uses the exact URL and tries to locate it in the database.

Please let me know if you need help migrating!
Additionally, please let me know if you're using FMTC within a proprietary or open source application.

Seems to be unrelated to the cache system, uncommenting it all still makes the error.

When launched the app first time, a popup came from bottom of screen before app opened asking if i wanted to clear cache, i said yes and then it stopped working.

Never seen that before, but if it's not caused by fmtc, I can't do very much.

[iBuaSpaz]

just incase someone else searches this.
added this to android/app/build.gradle

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug

•        shrinkResources false
  

•        minifyEnabled false
    }
  

  }

and it runs, it seems :)

Just because im curious, IF i where to want to use this to save some time, and of course include that this uses your cache system and link to click, what would this cost me? im just a hobby programmer, and not even sure anyone would use my app so..

Ah great, I might add that to the docs. In terms of licensing, please get in touch at [email protected] so we can discuss this privatley. If you could give me an idea of what your app is, and roughly how many users you forecast, I'm sure we can agree something. If it suits you better, I'm happy to do a per user cost basis, instead of yearly.
