[BUG] The example app has dependency errors and build errors with 3.0.0 - beta 2

[graemep-nz]

Using the latest Flutter

The example app gets dependency errors using 3.0.0 - beta 2 as below (BTW, trying to use V2.21 flutter_html also gets errors with the latest Flutter)

_Resolving dependencies... Because every version of flutter_html_all from path depends on flutter_html from hosted and example depends on flutter_html from path, flutter_html_all from path is forbidden. So, because example depends on flutter_htmlall from path, version solving failed.

The example app pubspec.yaml has this

_dependencies:
  flutter_html:
    path: ..
  flutter_html_all:
    path: ../packages/flutter_html_all_

Changing pubspec.yaml to this

_dependencies:
  flutter_html: ^3.0.0-beta.2
    # path: ..
  flutter_html_all: ^3.0.0-beta.2_

gets rid of the dependency errors but gets half a dozen errors on building that all look like this - all from gesture_detector_builder.dart

/C:/Users/.../AppData/Local/Pub/Cache/hosted/pub.dev/flutter_math_fork-0.6.3+1/lib/src/widgets/selection/gesture_detector_builder.dart:186:20: Error: The argument type 'void Function(TapDownDetails)' can't be assigned to the parameter type 'void Function(TapDragDownDetails)?'.

I was able to get rid of the build errors in 3.0.0-beta2 by changing pubspec.yaml in \hosted\pub.dev\flutter_html_math-3.0.0-beta.2 to use 0.7.1 of flutter_math_fork

dependencies: flutter_math_fork: ^0.7.1

When I was finally able to run the example app I got a weird error as below. I found that if I comment out the table extension, the error goes away and the example app works as expected

        extensions: [
        ...   
         //  const TableHtmlExtension(),  <<< comment this line to avoid the exception below

The following assertion was thrown during performLayout():
BoxConstraints forces an infinite width.

The offending constraints were: BoxConstraints(w=Infinity, 0.0<=h<=Infinity)
The relevant error-causing widget was: 
  Container Container:file:///C:/Users/gp/AppData/Local/Pub/Cache/hosted/pub.dev/flutter_html-3.0.0-beta.2/lib/src/css_box_widget.dart:74:9```

Also I'm building for a web app and running in google chrome.

For flutter web projects, the flutter_widget_from_html package can be used.

[graemep-nz]

Thanks. It would be helpful if the documentation on pub.dev for the two packages referenced each other. Is there anything for desktop - Windows & Macos?

[graemep-nz]

Do you have any idea what is the difference between these ? https://pub.dev/packages/flutter_widget_from_html_core https://pub.dev/packages/flutter_widget_from_html They're by the same person.

From the package's page:

The flutter_widget_from_html package supports most common HTML tags for easy usage. If you don't want to include all of its dependencies in your build, it's possible to use flutter_widget_from_html_core with a subset of the mixins to control your app size.

[graemep-nz]

Ah. Missed that. Thanks very much.

Example project still throwing dependency error, any possible fix?

Because every version of flutter_html_all from path depends on flutter_html from hosted and example depends on flutter_html from path, flutter_html_all from path is forbidden. So, because example depends on flutter_html_all from path, version solving failed.
