    go_router custom transition performance

    I'm trying to implement the OpenContainer transition for go_router in Flutter. It seems like no matter what I do, the end result is choppy. :/

    I'm using the native Transition widgets as well as the relatively new SnapshotWidget, but to no avail. Should I maybe use a custom painter? Would that improve performance?

    Please take a look at the code below and let me know if you see any ways that I could improve performance.

    Here's my attempt at an OpenContainer transition for go_router: 

     undefined
        
import 'package:flutter/material.dart';
import 'package:your_project_name_xxx/ui_models/container_transition_extra.dart';

class ContainerTransition extends StatefulWidget {
  final ContainerTransitionExtra extra;
  final Animation<double> animation;
  final Widget? sourceWidget;
  final Widget targetWidget;

  const ContainerTransition({
    super.key,
    required this.extra,
    required this.animation,
    required this.sourceWidget,
    required this.targetWidget,
  });

    Hive CE 2.11.0-pre: Introducing IsolatedHive for Safe Multi-Isolate Usage!

    Hey Flutter devs! I'm excited to announce the release of Hive CE v2.11.0-pre, introducing a new interface called IsolatedHive—a safe way to use Hive across multiple isolates.

    What's New:

    • IsolatedHive Interface: Enables safe Hive usage across isolates by maintaining its own dedicated isolate for database operations. It utilizes an IsolateNameServer behind the scenes to locate the Hive isolate.
    • Flutter Integration: Simply call IsolatedHive.initFlutter from hive_ce_flutter to automatically set things up to use Flutter's built-in IsolateNameServer.
    • Generated Extensions: The latest hive_ce_generator now provides the same easy-to-use registerAdapters extension on IsolatedHive.

    Why Use IsolatedHive?

    You might already be using isolates without realizing it! Common Flutter scenarios benefiting from isolate-safe Hive:

    • Desktop apps with multiple windows
    • Background task handling (flutter_workmanager, background_fetch, etc.)
    • Push notifica

    Simplify Dart & Flutter Isolate Communication with isolate_channel

    Hi everyone!

    I've just released a new Dart package: isolate_channel. It provides a simple and familiar API for handling communication between Dart isolates, directly inspired by Flutter's MethodChannel and EventChannel APIs used for native plugin communication.

    If you've ever found Dart isolate communication cumbersome or unintuitive, isolate_channel streamlines this process, making it feel as straightforward and familiar as working with Flutter plugin channels.

    I built this package to prepare for upcoming isolate support in Hive CE, and it made that work a lot easier!

    Check it out here: isolate_channel

    I'd love your feedback or contributions!

    Script for Flutter Doctor to recognize Android Studio flatpak

    cross-posted from: https://lemm.ee/post/56160274

    I install Android Studio via flatpak, and this can cause flutter doctor to not be able to determine the version or to not recognize the installation at all. I've managed a hacky fix for this by running a few commands that I run as a simple script that I'm sharing here. If you use this, just close Android Stuido after it is opened; it seems to just need to be opened once in order to be recognized by flutter doctor. 

     sh
        
#!/bin/bash

flutter config --android-studio-dir=/var/lib/flatpak/app/com.google.AndroidStudio/current/active/files/extra/android-studio

/var/lib/flatpak/app/com.google.AndroidStudio/current/active/files/extra/android-studio/bin/studio

    Installing flutter on linux immutable distro

    Hi! I'm a flutter developer and I've recently switched from Ubuntu to Bluefin (based on Fedora Silverblue) I was trying to install flutter and all the dependencies it asks for when running flutter doctor and while for clang++, cmake and ninja I have been able to install them with Homebrew (brew install llvm cmake ninja) and the warning went away, flutter seems not to detect GTK 3.0 development libraries when installed through homebrew (brew install gtk+3)

    After having looked a little bit online, I've seen that the problem is probably that it's searching the libraries in the wrong place and in fact even when I run pkg-config --modversion gtk+-3.0 I see the library as missing. Therefore, I tried setting the PKG_CONFIG_PATH env variable to the folder where brew installed my libraries (/home/linuxbrew/.linuxbrew/opt/gtk+3/lib/pkgconfig) and after that the output of the pkg-config program above is the one expected. However, this doesn't seem to

    🚀 Hive CE 2.8.0 Released: Streamlined Code Generation with GenerateAdapters & New Migration Tool!

    Hello Flutter community! I am proud to announce that I have released the largest update to Hive Community Edition yet. Version 2.8.0 adds support for the new GenerateAdapters annotaiton which greatly improves the code generation experience. With the GenerateAdapters annotation, you only specify the classes you want to generate adapters for. No more manually annotating every type and field and keeping track of their IDs.

    I also developed a migration tool to help transition from the old annotations. This migration tool makes sure your model classes do not have commmon issues that would result in data integreity issues and then generates the necessary files.

    You can see the documentation for the update here: https://pub.dev/packages/hive_ce#store-objects

    Seeking feedback on a much easier method of generating Hive TypeAdapters

    Hello! I'm the maintainer of Hive Community Edition.

    I am proposing to introduce a new annotaiton called @GenerateAdapters. This allows you to generate TypeAdapters for types without explicitly annotating any types or fields. This is much easier to maintian and also allows generating adapters for types outside the current package.

    For example: 

     dart
        
@GenerateAdapters([
  AdapterSpec<ClassSpec1>(),
  AdapterSpec<ClassSpec2>(),
  AdapterSpec<EnumSpec>(),
])
void _() {}

    This will generate type adapters for all the types specified. The main difference between using @GenerateAdapters and explicit annotations is that type IDs and field indexes are determined automatically. This information is then stored in a hive_schema.yaml file which informs future generations which type IDs and field indexes are in use.

    My main concern is introducing this feature in a way that allows any future changes to be non-breaking. I believe I have eliminated mo
