flutter analyze fails on v1.1.8

[gbloggs]

After upgrading to v1.1.8 and running analyze, the analyze is failing with the following error:

flutter analyze

I'm not sure what this file does but seems very web related:

The generated file looks like this:

you can try and exclude generated_plugin_registrant.dart from analysis, this worked fine for me.

just add in project root a file named analysis_options.yaml with the following content:

analyzer:
  exclude: [lib/generated_plugin_registrant.dart]

Hi... That makes sense, and has meant the the analyze passed. Is there a way to tell the build not to include this plugin? We use many more plugings, but it seems to have only included ones that have an _web component, which this bluetooth printer one does not. I think I understand why it was failing the analyze, there is no web plugin, but we have used this plugin for a few months now and this has only just happened, from v1.1.8.

Furthermore, whilst adding the exclude allows analyze to pass, building for web fails:

flutter build web

💪 Building with sound null safety 💪

I've just updated flutter. The issue remains in 2.5.2 too:

Ok. Further to this, iOS builds are failing too for me.

Getting the following build error in Runner/GeneratedPluginRegistrant.m:

//
// Generated file. Do not edit.
//
// clang-format off
#import “GeneratedPluginRegistrant.h”
#if __has_include(<blue_thermal_printer/FlutterBluePlugin.h>)
#import <blue_thermal_printer/FlutterBluePlugin.h>
#else
@import blue_thermal_printer;
#endif

This issue was even causing me in building the android app as well not letting me to build my web also. I contacted the developer of this package and he upgraded the version from 1.1.9 to 1.2.0 and now everything works fine. Thanks to the developer for his wonderful support.
