Flutter, Firebase and Admob Mediation
I've been looking through the interwebs and haven't found anything. Any insights here? I want to add AdMob Mediation to my Flutter app. It is weird to be that Firebase/AdMob doesn't have Flutter specific information to get AdMob Mediation to work since it is also a Google property.

Listening for Keyboard open/close with position for Animation?
So I've been diving into Flutter recently and sometimes I'm really really excited by it. Coming from React Native, it's so nice to know what I am making will look the same on both devices! The granularity of control with the widgets is fun, even though it can be a bit verbose.One thing that I really love about React Native is the simplicity of doing basic animations. Set an Animated value, add an interpolator, and Animate stuff.But I digress.Flutter, while it's certainly easier to do very complex animation as opposed to React Native, I feel is missing some very basic things. Right now I'm porting over an app from React Native. On the login screen, when you focus the textfield, the logo above it shrinks as the keyboard rises. Its height is literally determined by the keyboard height thanks to the Keyboard class having a listener method.I've been looking all over for something similar to Flutter and I'm at a loss. I know you can get the `MediaQuery.of(context)` to get all sorts of values, and also the WidgetsBindingObserver, but I've had no luck of either getting the bottom value 'as' it changes, or the keyboard position.Has anyone done something similar?

Mimic Google UI from Google calendars?
I want to do this. I have a Stream Builder using Firebase with a list of events with dates and times. I want to group events under a specific date and start the feed at the current date but still allow the user to scroll in the past or the future. [image: IMG_0EFE2611AD60-1.jpeg] I am assuming

Flutter Search widget
Hi, I have developed a flutter package named SEARCH WIDGET. This package provides a Search Widget for selecting an option from a data list. It also provides filtering of list items based on the search text.Learning:
- Use of overlays (popup in this widget)
- Use of CompositedTransformTarget (used in scrolling overlays)
- Use of Render objects and how overlays are positioned
- Learning of typedefs (for beginners)Pub: https://pub.dartlang.org/packages/search_widgetSource code: https://github.com/apgapg/search_widget (Dont forget to )Happy Fluttering! ❤️

Problem/issues I want to talk about. Firestore related
Hey everyone. I hope this wont get deleted. most of my posts do on this sub-reddit. To rule number two, I am not technically asking for help. I am wanting to talk about a design.Using the cloud_firestore plugin, we are given a cache. When we do a query, the query resultant is saved into the cache. Now, when we execute the same query. We retrieve the result from out cache as expected but there is a limit and we need to talk about this limit. The limit is 30 minutes. You can only use cache content for 30 minutes while ONLINE. When you are offline, you are allowed to use previously caches queries.So lets say, i load 50 documents throughout my app(different page routes). For the next 30 minutes, we can keep going through the app to get those 50 documents(havent changed and they are static). After 31 minutes, the queries will be issues as brand new query and will be charged(an additional charge of 50 reads) for the OLD 50 DOCUMENTS(that havent changed).I google this issue, some people are mentioning and the only replies that they get is, always something along the lines of, "please post your code, this shouldnt be happening".Very easy code to replicate, a tutorial from google themselves: https://codelabs.developers.google.com/codelabs/flutter-firebase/index.html?index=..%2F..index#10All youtube video showing off how to use cloud firestore, i ran their code and same issue.How to fix this? I am coming up with a plan of disabling firestore persistence and create my own cache with sqflite. Provide last_updated time stamps in documents. Design queries where they run queries of new documents updated by last_updated field. Whenever a new document has been updated, a listener will fire on client side and download the document. Then I use this documents ID to update my saved document in SQFlite.Do I have to do this, or there is no bug and only affects me?​I have used BLoC pattern, google tutorial pattern of multiple widgets where streambuilder is at top most ... etc.​Is this acceptable? A user looking at profiles of his/her friends on their phone. Lets say this user is looking through 50 of his friends profiles(1 BY 1) 3 times a day spaced 2 hours apart. thats about 150 reads per day while it should be only 50 for the initial download and read from cache IF NO CHANGES.​I do have pagination enabled where I have a limit of 10 documents per page. But who cares when a user will always open the app 4-5 times throughout the day at spaced more than 30 minutes apart causing new queries causing more reads(downloads as well, waste of bandwidth from user point of view)​some links of others raising issue: cant find them all for nowhttps://stackoverflow.com/questions/51317606/how-do-i-store-a-firestore-document-locallyhttps://stackoverflow.com/questions/55013944/cloud-firestore-keeps-re-downloading-documents-flutter
