[BUG] Web: Refused to set unsafe header "User-Agent"

[d1ss0nanz]

What is the bug?

There seems to be a regression in v5 that is trying to set the User-Agent header on web.

How can we reproduce it?

Use flutter_map in web application.

Do you have a potential solution?

No response

Platforms

Flutter Web on Chrome

Severity

Minimum: Allows normal functioning

Hey @d1ss0nanz,
We're aware of this, and did this intentionally in order to simplify the code base. This shouldn't cause any issues.

I've worked around this behaviour by implementing a custom TileProvider that removes the User-Agent header in getImage.

@JaffaKetchup Why not just make the userAgentPackageName nullable? So then we can just set it to actually empty instead of 'unknown'.

flutter_map/lib/src/layer/tile_layer/tile_layer.dart

Line 277 in 9211d54

String userAgentPackageName = 'unknown',

flutter_map/lib/src/layer/tile_layer/tile_layer.dart

Lines 299 to 301 in 9211d54

	tileProvider = (tileProvider ?? NetworkTileProvider())
	..headers.putIfAbsent(
	'User-Agent', () => 'flutter_map ($userAgentPackageName)'),

It spams the console log.

I guess if this is really bothering people, it may be possible just to check kIsWeb. I'll make a PR at some point.
