![]() It provides a straightforward way to perform basic (CRUD) operations.It’s the most efficient database in terms of speed and performance compared to SQFlite and SharedPrefrences.Somewhere in your lib/folder, you can make your model file. ![]() You can manually compose your Type Adapters, yet we’ll generate our own with the hive_generator and build_runner packages we added to our dev dependencies earlier. To utilize these model kinds, you need to enroll TypeAdapters, which causes you to encode/decode your item to binary form on a disk. Hive permits you to store most standard types - String, int, Map, List, DateTime, yet you need to have a model class for your data since this makes development a lot simpler and quicker. You can call Hive.openBox(‘name’) regardless of whether you as of now have the box opened elsewhere, here and there it very well might be smart to do this. Box (‘name’), where ‘name’ is the name of the case (saying the DB name). Boxes can be opened with await Hive.Openbox(‘name’) can get an instance of an opened box with Hive. With hive, before you can read/compose data, a box should be opened. I like to see boxes as an organizer with files listed and arranged by a numbering framework or as normal maps in the dart. Hive stores its data in boxes containing key-value sets. Make sure all probabilities add to 1 and you are good to go.In this screenshot of the demo, there was a to-do list, and all red color tick will show progress, and the purple tick will show completed and we also used filter the data using Hive in your flutter applications. ![]() So there you go, when in doubt draw a tree diagram, multiply along the branches and add the columns. You can see more uses of tree diagrams on Conditional Probability. One final step: complete the calculations and make sure they add to 1: (When we take the 0.6 chance of Sam being coach and include the 0.5 chance that Sam will let you be Goalkeeper we end up with an 0.3 chance.)īut we are not done yet! We haven't included Alex as Coach:Īn 0.4 chance of Alex as Coach, followed by an 0.3 chance gives 0.12.Ġ.3 + 0.12 = 0.42 probability of being a Goalkeeper today Here is how to do it for the "Sam, Yes" branch: This is done by multiplying each probability along the "branches" of the tree. The tree diagram is complete, now let's calculate the overall probabilities. If you get Alex, there is 0.3 probability of being Goalie (and 0.7 not): Now, if you get Sam, there is 0.5 probability of being Goalie (and 0.5 of not being Goalie): The probability of getting Sam is 0.6, so the probability of Alex must be 0.4 (together the probability is 1) First we show the two possible coaches: Sam or Alex: So, what is the probability you will be a Goalkeeper today? about 6 out of every 10 games (a probability of 0.6).
