Since I updated the way the tree behaves, it may be better now.

4 years ago Same issue for me. Tried prerelease version but it falis with:
../../../../../../.pub-cache/hosted/pub.dartlang.org/device_preview-0.5.0-prerelease.4/lib/src/tool_bar/format.dart:4:8: Error: Error when reading '../../../../../../.pub-cache/hosted/pub.dartlang.org/meta-1.1.8/lib/meta_meta.dart': No such file or directory

icon: Icons.phonelink_setup_outlined,
^^^^^^^^^^^^^^^^^^^^^^^^
It seems like an environment problem on your side.
Which version of flutter do you use ? Can you run a flutter clean ?
(I published a new prerelease version).

4 years ago @aloisdeniel I experimented a bit more and fount out what caused this error. Before running the app we initialized date formatting with initializeDateFormatting('ru_RU').then((_) => runApp(...) from intl package. If I remove this line then your library works without an error. However I would still like to be able to use initializeDateFormatting 🤔
Using Flutter 1.22
UPD: I moved initializeDateFormatting('ru_RU') call into a builder of DevicePreview and it's all working now. I was a bit afraid that I should only start my app after initializeDateFormatting resolved it's Future, but turns out that this method is actually synchronous and only returns new Future.value(null) for some weird reason.
So this set up helped me fix the issue:
runApp(DevicePreview(
enabled: !kReleaseMode,
availablesLocales: [NamedLocale('ru', 'RU')],
builder: (context) {
initializeDateFormatting('ru_RU');
return MyApp();
}));

2 years ago got the same error.
found out that it only occurs when I'm using this method here from the "intl"-package somewhere in my code (directly or any package that uses it):
initializeDateFormatting('de_DE');
and I need to use this method when working with non-english Locales (in my case for formatting dates)
and the initiator of this issue @riccardocalligaro is also using the "intl" package, so it seems that it's the same problem
This is the Stacktrace i get:
The following UnsupportedError was thrown building Positioned(left: 0.0, top: 0.0, right: 0.0, bottom: 0.0):
Unsupported operation: Cannot modify unmodifiable map
The relevant error-causing widget was:
Positioned Positioned:file:///C:/flutter/.pub-cache/hosted/pub.dartlang.org/device_preview-1.0.0/lib/src/device_preview.dart:599:36
When the exception was thrown, this was the stack:
#0 _UnmodifiableMapMixin.[]= (dart:collection/maps.dart:269:5)
#1 initializeDateFormattingCustom (package:intl/date_symbol_data_custom.dart:35:19)and this is the most basic example for reproduction:
import 'package:device_preview/device_preview.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:intl/date_symbol_data_local.dart';
import 'package:intl/intl.dart';
void main() => runApp(
DevicePreview(
enabled: !kReleaseMode,
builder: (context) => MyApp(), // Wrap your app
),
);
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
initializeDateFormatting('de_DE');
return MaterialApp(
useInheritedMediaQuery: true,
locale: DevicePreview.locale(context),
builder: DevicePreview.appBuilder,
home: MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(
children: [
Text('${DateFormat('E, dd.MM.yyyy', 'en_US').format(DateTime.now())}'),
Text('${DateFormat('E, dd.MM.yyyy', 'de_DE').format(DateTime.now())}')
],
),
),
);
}
}@aloisdeniel is that something you can fix on your side?

2 years ago I am still facing this issue using the current 1.0.0 . How did you guys fixed this?

commented
2 years ago by not using the 'intl' package
sawirricardo
commented
2 years ago @filly82 but then how do you configure the intl package?
filly82
commented
2 years ago when you don't use it then you don't need to configure it :)
in my case it was following method that caused the problem, so I don't use it anymore
initializeDateFormatting();
in your case it could be another method from the package that is causing the error.

2 years ago @sawirricardo look at @makstheimba post for a temporary fix if you are using the intl-package directly
in my case that is not possible, because i am not using the package directly, I use another package that uses the intl-package
sawirricardo
commented
2 years ago @filly82 , I used it directly, though. But it's true that if I take out the initializeDateFormatting(), the app compiles successfully. But, it seems not a good fix.
filly82
commented
2 years ago @sawirricardo Have you read the post from @makstheimba completely? No need to take the method out, you have to relocate it
sawirricardo
commented
2 years ago @filly82 Done that, but no luck. It still errs due to either "directionality" widget or Positioned widget. Both of them under error Unsupported operation: Cannot set value in unmodifiable Map.
