Error output

Using hover build [...] --XXX to build my application, I get the following
error:

hover: Generating kernel snapshot
result 97ec1709-f58d-434b-b3b3-f41ff40bad12
Error: Error when reading '.packages': No such file or directory
Error: Error when reading '.packages': No such file or directory
[...]

How to reproduce?

$ flutter create testapp
$ cd testapp
$ flutter run --device-id linux # confirm that the app runs
$ hover init
$ hover build linux # press y when asked

Build will fail.

to fix:

create generate_dot_packages.dart in project root directory with following content:

import 'dart:convert';
import 'dart:io';

Future<void> main() async {
  File file = File(".dart_tool/package_config.json");
  dynamic pkgconfig = jsonDecode(await file.readAsString());
  List<dynamic> pkgs = pkgconfig["packages"];
  for (var elm in pkgs) {
    if (elm["rootUri"] == "../") {
      elm["rootUri"] = "./";
    }
  }
  pkgconfig["packages"] = pkgs;
  print(jsonEncode(pkgconfig));
}

run:

$ dart run generate_dot_packages.dart > .packages

hover build linux-appimage should work.
