Hello to all! I am creating a multi-language application. However, I do not find a tutorial on the web that would explain how to do it. I found tutorials to make a multi-language application for one page, but for many, I did not find. Do you have any suggestions? I want to detect the device

Hello fellow Flutter devs!​I've started writing a free book about testing Flutter applications and I would like to hear from you if there are some areas that you think should be covered. I want to create a project from start to finish using TDD and share as much knowledge I've gained about testing (finding elements, interacting with widgets, mocking API etc.).​Are there any problems you've encountered while writing tests and didn't know how to deal with? I'm looking forward to hearing from you

LimitedBox gives children boundaries when parents don't.

<b>Dart is held back by its lack of third and first party tooling, and the Google Photos API should expose a gRPC endpoint</b>
<strong>tl;dr</strong> Writing API clients in Dart is boring and hard -- gRPC makes it easy. Google doesn't expose a gPhotos gRPC endpoint, nor do they expose useful files/tools to generate a Dart REST API client from a machine-readable service definition. They shoulddo one or the other -- exposing gRPC endpoint is probably easier given the current state of affairs.This is the story of my short journey into trying to write a Google Photos API client. This is not advice, strictly speaking, it's more a plea and excitement for the future of Dart and Google Photos.I'm thrilled to see Google Photos finally expose a Photos API after Google sunset <a href="https://picasa.google.com/">Picassa</a> and its API several years ago. This is a major step in the right direction.<strong>The current state of gPhotos affairs</strong>Google released a <a href="https://github.com/googlecodelabs/photos-sharing/tree/final/">codelab</a> demonstrating the (relatively new) Google Photos API in a Flutter app. It uses the <a href="https://developers.google.com/photos/library/reference/rest/">Google Photos REST api</a>, and as far as I can tell, they had to build all of the <a href="https://github.com/googlecodelabs/photos-sharing/tree/final/lib/photos_library_api">wiremodel classes</a> by hand and then build_runner to generate the JSON serialization methods. This is because gPhotos doesn't actually expose a gRPC gateway.<em>It's tiresome to do this type of API client generation by hand. This is the kind of thing that makes developers not want to use your API and/or quit their jobs.</em><strong>Some gRPC gateway exists, but we can't use it</strong>Google actually seems to have gRPC working -- nearly all service-to-service communication within Google datacenters is powered by protobuf -- it's just hidden from external devs. The <a href="https://imgur.com/3H4veYh">API docs seem to hint</a> at a gRPC service hidden behind a JSON transcoding gateway, and the official Java docs include <a href="https://github.com/google/java-photoslibrary/blob/0014b569f725ff801ff36e32266479442c850119/photoslibraryapi/src/main/java/com/google/photos/library/v1/proto/AddEnrichmentToAlbumResponse.java#L2">files clearly generated from .proto files</a>. In fact, most Google services do expose gRPC interfaces, and their .proto definitions are publically available in <a href="https://github.com/googleapis/googleapis">this repo</a>.<em>This is proof positive that Google has a gRPC gateway hidden behind a firewall. Why not expose it? This is a solved problem for teams at Google.</em><strong>Going for broke -- can I at least autogenerate a REST API client?</strong>Even without a gRPC endpoint, these proto files could still be used to automatically generate the json wiremodels that Google seems to have hand written for their codelab. However, the path reference in the above Java file (google/photos/library/v1/**.proto) is not included in Google's publicly released proto files repo.<em>So the answer currently is "no, we cannot autogenerate REST API clients for gPhotos from gRPC def'ns."</em><strong>Maybe there's some hope?</strong>Google does, however, offer a <a href="https://developers.google.com/discovery/v1/reference/apis">discovery document</a> for the Google Photos APi. It's located <a href="https://photoslibrary.googleapis.com/%24discovery/rest?version=v1">here</a>. Some tools currently exist that claim to generate API clients from discovery documents. The two that currently exist are written by Google:<a href="https://github.com/googleapis/gapic-generator">gapic generator</a><a href="https://github.com/google/apis-client-generator">apis clients generator</a>The "gapic generator" is the more broadly supported of the two, but is useless for Dart developers. No Dart support whatsoever, and regardless, Java is the only supported…

Video_Player Package on iOS has a really annoying bug
I want to use the video_player plugin to display one simple video on the home_screen of my app. I've implemented the player and it works perfectly until, when i exit the app on my iphone and then open it again, the video player turns into a white screen. Same thing happens if i navigate to another page on my app and then come back to the home page, also when I slide the Control Center on my phone. This only happens on IOS and when the video is PAUSED.Now if I run my app on the android simulator, this problem disappears but the audio in the video starts way before the video itself.I won't bore you with the code because its the same exact implementation of the plug-in's example on github.Here is a gif showing the issue: https://giphy.com/gifs/eMOy0qS09WpoAEADDlI have no clue on what might be causing this, is there a way I can fix this ?Thanks
