LayoutBuilder does not support returning intrinsic dimensions, started in v0.8.0

[absar]

The following error started after upgrading to v0.8.0

Code sample

import 'package:confetti/confetti.dart';

void main() {
  runApp(
    MaterialApp(
      home: Scaffold(

Error

The following assertion was thrown during performLayout():
LayoutBuilder does not support returning intrinsic dimensions.

Calculating the intrinsic dimensions would require running the layout callback speculatively, which might mutate the live render object tree.
The relevant error-causing widget was:  AlertDialog AlertDialog:/confetti/confetti_layout_builder_issue.dart:29:25
When the exception was thrown, this was the stack: 
#0      _RenderLayoutBuilder._debugThrowIfNotCheckingIntrinsics.<anonymous closure> (package:flutter/src/widgets/layout_builder.dart:399:9)

Looks like it's related to this flutter/flutter#46063

@HayesGordon @funwithflutter can you have a look at this?
