Usage

    final nativeResolver = DivExpressionsResolverPlatform.instance;
    
    // Use simple math
    fianl r1 = await nativeResolver.executeExpression(
        "@{2 + 2}",
        context: {},
    );

    // Use variables
    fianl r2 = await nativeResolver.executeExpression(
        "@{a + b}",
        context: {
            "a" : 2,
            "b" : 2,
        },
    );

    // Use embedded functions
    fianl r3 = await nativeResolver.executeExpression(
        "@{sum(a, b)}",
        context: {
            "a" : 2,
            "b" : 2,
        },
    );
    
    // Use branching and more!
    fianl r3 = await nativeResolver.executeExpression(
        "@{sum(a, b) == 2 ? 2 : -1}",
        context: {
            "a" : 2,
            "b" : 2,
        },
