Hide misleading source context errors from Dart/Flutter SDK for Flutter Web

[buenaflor]

Description

source context is automatically enabled on Flutter web when using the sentry_dart_plugin.

When correctly using the plugin it will upload sourcemaps and sources which leads to the source code of the own app displayed inbetween minified third party package code.

However, the issue will still show misleading missing_source_context errors which are irrelevant because they refer to sources not from inApp but the flutter/dart sdk.

@lforst do you have a suggestion on how to approach this - do we just conditionally hide it if they're not relevant? Also feel free to tag someone else who knows better

@loewenheim I feel like symbolicator should not be emitting the error here. Looks like everything got mapped correctly. I'd assume flutter web uses inline-source maps.

@lforst release builds generate a sourcemap that we also upload

example:

Just saw that the source maps references always point to main.dart.js.map. Generally speaking all js files need to have their own .map files. This looks off.

Hm, this is the only sourcemap generated by flutter, what do you think about disabling the error messages manually for now until we can investigate this more? It's pretty bad for the ux currently

If the error messages are not actionable, not informative or even wrong we should hide them for sure!
