Dime Flutter package
Bringing Dime dependency injection to Flutter with usable helper methods and Widgets.
Getting Started
Take a look at Dime package for BaseModules and definitions.
Use DimeScopeFlutter to wrap child widget with Dime Scope and provide list of modules for that scope.
Root Scope modules are always fallback to.
Use DimeFlutter.scopeOf(...) as inherit widget to fetch DimeScope to get instances you need down the tree.
Dime Scope fetch up the tree examples:
Test class to be referenced by main scope_test.dart tests.
Modules:
| Module | Instance |
|---|---|
| ModuleA | AA() |
| AB() | |
| AC() | |
| ModuleB | BA() |
| BB() | |
| BC() | |
| ModuleC | CA() |
| CB() | |
| CC() | |
| ModuleXX | AA() |
| BB() | |
| CC() |
Scope graph:
| Root Scope | Modules/Scopes | Modules/Scopes | Modules/Scopes |
|---|---|---|---|
| Dime | - ModuleC | ||
| - ModuleXX (override) | |||
| - scope1 | - ModuleA | ||
| - ModuleB | |||
| - scope2 | - ModuleA | ||
| - ModuleC | |||
| - scope 21 | - ModuleC | ||
| - scope 22 | - ModuleA | ||
| - ModuleB |
Example injections:
scope2.inject<CA> - from scope2.ModuleC.CA
Dime.inject<CA> - from dime.ModuleC.CA
scope1.inject<CA> - from dime.ModuleC.CA
scope1.inject<AA> - from scope1.ModuleA.AA
scope2.inject<BC> - not found - can't access other scopes
scope2.inject<AB> - from scope2.ModuleA.AB
Dime.inject<AA> - dime.ModuleXX.AA
Dime.inject<AB> - not found - Dime can't drill to scopes
Dime.inject<CC> - dime.ModuleC.CC
scope21.inject<AA> - scope2.ModuleA.AA
scope21.inject<CC> - scope21.ModuleC.CC
scope22.inject<AC> - scope22.ModuleA.AC
scope22.inject<CB> - scope2.ModuleC.CB
scope21.inject<BB> - dime.ModuleX.BB
