Build failed after pub get map_launcher plugin

[edgarjc]

I copied map_launcher: ^1.1.3 into my pubsec.yaml, clicked pub get and my application (IOS and Android) throws errors. If I revert changes before I used map_launcher: ^1.1.3 my application works again. Has anyone had this issue before?

It worked after upgrading my gradle version from 3.5.0 to 3.5.4

This worked for the android version. Upgraded from 3.5.0 to 3.5.4 but still having issues with the IOS application.

The issue is that flutter created an old ios project that's based on obj-c rather than swift. You could try in xcode add a new obc-c file and xcode will ask to create bridging header, click yes and this will solve the issue.

Solution: #49

Ha I just finished texting but you already found a solution :)
Glad it worked out

Changing the gradle version to 3.5.4 solves this problem but creates another one. I also include google_maps plugin, and that fails on certain Android devices when you upgrade to 3.5.4.

I already have a bridging header in my Xcode project and this is still causing a problem. @edgarjc
