How to resize toolbar buttons simultaneously/globally?

[hardiklakhalani]

I do understand about dos & don'ts of material design but I need to override the all the default given & custom button size & icon size to occupy the least possible space

import 'dart:convert';

import 'package:flutter/material.dart';
import 'package:remixicon/remixicon.dart';
import 'package:flutter_quill/flutter_quill.dart';
import 'package:vsc_quill_delta_to_html/vsc_quill_delta_to_html.dart';

class ReplyEditorWidget extends StatefulWidget {
  const ReplyEditorWidget({super.key});

  @override
  State<ReplyEditorWidget> createState() => _ReplyEditorWidgetState();
}

class _ReplyEditorWidgetState extends State<ReplyEditorWidget> {
  final QuillController _quillController = QuillController.basic();

  @override
  void dispose() {
    _quillController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Theme(
      data: Theme.of(context).copyWith(
       iconTheme: IconTheme.of(context).copyWith(size: 12), // This is changing the size of only the delete icon
      ),
      child: Column(
        children: [
          QuillSimpleToolbar(
            controller: _quillController,
            config: QuillSimpleToolbarConfig(
              toolbarSize: 10, // This is not making any difference
              customButtons: [
                QuillToolbarCustomButtonOptions(
                  icon: const Icon(Remix.delete_bin_3_line),
                  onPressed: () {
                    _quillController.clear();
                  },
                ),
              ],
            ),
          ),
          QuillEditor.basic(
            controller: _quillController,
            config: const QuillEditorConfig(
              placeholder: 'Enter message here...',
            ),
          ),
        ],
      ),
    );
  }
}

Have you tried the buttonOptions property which is in QuillSimpleToolbarConfig and of type QuillSimpleToolbarButtonOptions? It accepts base which allows you to change common properties for all buttons.

// Example
QuillSimpleToolbar(
  controller = _controller,
  config = QuillSimpleToolbarConfig(
    buttonOptions: QuillSimpleToolbarButtonOptions(
      base: QuillToolbarBaseButtonOptions(
        iconSize: 20,   
      ),
    ),
  ),
)
