The author should really be editing it. :) – Dupe

Answer 1

I was dealing with this error. In my case, it was because there was a dependency that was not compatible with flutter 2.5. I tried many solutions. But only this worked for me.

First add this to your pubspec.yaml

 charts_flutter:
    git:
      url: git://github.com/google/charts.git
      path: charts_flutter

as described on this link.

If you have an error saying: remote end hung up unexpectedly while git cloning,

then run this commands

git config --global http.postBuffer 500M
git config --global http.maxRequestBuffer 100M
git config --global core.compression 0 

as described on this answer.

This solved my problem.

Answer 2

Add them in dependencies and remove body1 from bodyText1

charts_flutter:
    git:
      url: git://github.com/google/charts.git
      path: charts_flutter

Answer 4

The error thrown on the logs seems to be thrown by the plugin that you're using: place_picker-0.9.19-nullsafety. The logs indicate that the issue comes from Theme.of(context).textTheme.body1

Checking the Flutter docs, body1 on TextTheme is defined as bodyText1. You might want to consider updating how body1 is being called in TextTheme. Otherwise, you can track this issue ticket filed on GitHub related to this issue.

Answer 5

Edit the lines in the dart package like below and it will work. Of course the author should do this, but you can edit it yourself as well :)

rich_suggestion.dart

Original: TextSpan(text: boldText, style: style.copyWith(color: Theme.of(context).textTheme.body1!.color)),

New: TextSpan(text: boldText, style: style.copyWith(color: Theme.of(context).textTheme.bodyText1!.color)),

search_input.dart

Original: Icon(Icons.search, color: Theme.of(context).textTheme.body1!.color),

New: Icon(Icons.search, color: Theme.of(context).textTheme.bodyText1!.color),

Answer 6

replace all in files ctrl + shif+ r "Theme.of(context)" with => ThemeData()

Answer 7

Guys usually we add dependencies before importing. but in this case first import that file(import 'package:charts_flutter/flutter.dart' as charts;) after that hover on package, it will give a option to add the dependencies then add the dependencies in this way. then your error will be solved.
